In the production and application of multi-color paints such as industrial paints, floor coatings, and anti-corrosion coatings, "floating/flooding" and "pigment settling" are two persistent challenges most frequently encountered by formulation engineers and procurement personnel. Uneven color affects product appearance consistency, while hard settling leads to application difficulties, performance degradation, and even waste. Traditional single-function additives often address one issue at the expense of the other. The innovation of Anjeka's Anjeka-6104S lies in its unique "controlled flocculation" mechanism, combining excellent anti-floating/flooding capability with significant anti-settling effect into one, providing a one-stop solution for the long-term stability of multi-color paint systems.   I. In-Depth Analysis of Pain Points: The Root Causes of Floating, Flooding, and Settling Floating and flooding essentially result from the separation of colors caused by the different migration rates of various pigments (such as titanium dioxide, organic pigments, and carbon black) during film drying, due to differences in particle size, density, and surface polarity within the system. Hard settling, on the other hand, occurs due to insufficient pigment dispersion stability, leading to aggregation and sinking under gravity during storage. The two often occur together, jointly challenging the stability and application properties of the coating system.   II. Core Solution: The Unique "Controlled Flocculation" Technology Anjeka-6104S does not achieve stability by completely isolating pigment particles but creatively employs the principle of "controlled flocculation." It enables the formation of a loose, controlled network flocculation structure between different pigments and extender pigments. This structure12: Locks in Color: Effectively restricts the free movement of different pigment particles, thereby fundamentally preventing floating and flooding. Supports Particles: The formed three-dimensional network structure can support pigment particles, significantly slowing down or preventing the formation of hard settling12. Synergistic Effect: The product also contains polysiloxane copolymers, which further enhance the anti-floating effect and improve film surface leveling and slip. This can sometimes eliminate the need for additional silicone leveling agents.   III. Performance Verification: Multi-System Testing, Reliable Performance Laboratory data fully demonstrates the broad applicability and reliability of Anjeka-6104S: Broad-Spectrum Anti-Floating/Flooding: In multi-color paint tests using various resin systems such as thermoplastic acrylic, hydroxy acrylic, polyester, and epoxy, Anjeka-6104S effectively eliminated floating and flooding phenomena. Flexible Process Adaptability: Whether added before grinding (for better pigment wetting) or after grinding (for easy post-adjustment), its anti-floating/flooding effect has been verified, providing flexibility for the production process. Significant Anti-Settling Effect: In the same tests, Anjeka-6104S showed a reduction in pigment settling ratio, with the post-addition method yielding better anti-settling results in systems like acrylic and alkyd. Solving Practical Formulation Challenges: For common floating issues in gray systems (such as floating white or black) in floor coatings and industrial paints, Anjeka-6104S is listed by the technical team as an effective solution recommendation.   IV. Application Guide: How to Use Anjeka-6104S Efficiently Applicable Systems: Particularly suitable for solvent-based and solvent-free coating systems of medium to high polarity, such as epoxy, polyester, acrylic, and alkyd resins, widely used in industrial, architectural, anti-corrosion, and automotive coating fields. It can also be used in amine-neutralized water-based systems. Typical Problems: An ideal choice for solving floating when titanium dioxide is compounded with colored pigments, uneven color in gray paints, and preventing hard settling. Addition Recommendation: Generally added based on the total pigment content. Recommended ranges: titanium dioxide 0.5%-2.5%, inorganic pigments 3%-10%, organic pigments 10%-20%. It is recommended to add it to the grinding material first and disperse it thoroughly for optimal results. Stability is the cornerstone of coating quality. Facing the challenges of floating and settling in multi-color paints, choosing an additive with a scientific mechanism and proven effectiveness is crucial. Anjeka-6104S, with its unique "controlled flocculation" technology, provides you with a dual-effect stability guarantee.

In the "face project" of automotive coatings, the purity of color, the fullness of gloss, and long-term stability are the invisible benchmarks defining whether a product is "premium." However, issues like pigment agglomeration, floating and flooding, and storage thickening often become stumbling blocks on the formulator's path to perfection. The core often lies in—dispersion. Dispersion is not just about breaking pigments apart; it's about providing a long-term "home" for each pigment particle through scientific anchoring and stabilization. Anjeka Technology focuses on this, offering precise dispersant choices for different pigments and systems.   I. The "High-Standard" Test for Automotive Coatings: Why Dispersion is the Performance Cornerstone? With the automotive industry's shift towards electrification and intelligence, and rising consumer demands for vehicle appearance durability and color personalization, automotive coatings face unprecedented high-performance challenges: higher gloss and distinctness of image (DOI), superior weather and chemical resistance, more complex effect pigment applications, and environmental trends like water-based and high-solids formulations. These impose near-strict requirements on the dispersion state of pigments within the film. Poor dispersion directly leads to reduced tinting strength, loss of gloss, uneven color, and can trigger subsequent flocculation and settling, severely affecting the final film performance and long-term stability.   II. Precision Strategy: Different Pigments Require Different Dispersion "Keys" The diversity of pigment chemical properties means a "one-size-fits-all" dispersion approach is rarely effective. Based on in-depth research into pigment surface characteristics and dispersion mechanisms, Anjeka has built a targeted product matrix: Conquering "Carbon Black" and High-Surface-Area Organic Pigments: Anjeka-6164/A, with its powerful anchoring groups, tightly adsorbs onto surfaces like carbon black, providing excellent steric hindrance and electrostatic stabilization, effectively addressing issues like insufficient jetness, thickening, and floating/flooding caused by dispersion instability. Overcoming "Phthalocyanine" and Other Hard-to-Disperse Organic Pigments: For pigments like Phthalocyanine Blue and Green that are prone to flocculation, Anjeka-6161A demonstrates special efficacy. It significantly improves the deflocculation state of pigment particles, thereby releasing the inherent brightness and saturation of the pigment, resulting in purer, more vibrant colors. Efficiently Handling "Inorganic Pigments" and General Needs: For titanium dioxide and various inorganic color pastes, Anjeka-6176 offers a cost-effective solution, effectively reducing grinding viscosity, improving grinding efficiency, and ensuring storage stability. Anjeka-6050, as a versatile polymeric dispersant, provides good color development and gloss in many organic pigment systems. Adapting to "Solvent-Based" and "Water-Based" Dual-Track Systems: In traditional solvent-based and high-solids systems, Anjeka-6110/A shows good dispersion adaptability for high-polarity pigments.  III. Beyond Dispersion: Injecting Stable Genes into the Automotive Coating System The value of an excellent dispersant extends beyond efficiency gains during the grinding stage. Anjeka dispersants are designed with the entire lifecycle in mind: Enhancing Initial Performance: By optimizing pigment dispersion, maximizing pigment tinting strength and hiding power lays the foundation for high gloss and DOI. Ensuring Process Stability: Preventing pigment re-flocculation and settling during coating production, storage, and transportation ensures batch-to-batch consistency. Optimizing Application Performance: A good dispersion state aids coating leveling, reducing film defects caused by pigment issues. Supporting Long-Term Durability: A stable pigment dispersion system is the internal support for the film to resist erosion from UV light, humidity, heat, chemicals, etc., maintaining color and gloss for longer. The art of balancing color and performance begins with precise dispersion.

In the fields of industrial coatings, floor paints, and high-performance adhesives, color is not just about appearance; it is a direct reflection of quality and stability. However, from pigment grinding to the final film formation, issues such as insufficient pigment dispersion, storage thickening, and floating/flooding during application have long plagued formulation engineers and procurement decision-makers. Choosing an efficient dispersant has become key to ensuring product performance, reducing production risks, and enhancing market competitiveness. ANJEKA-6062B, a block copolymer dispersant specifically designed for solvent-based and solvent-free systems, is becoming a reliable partner for many companies in overcoming dispersion challenges with its excellent versatility, viscosity reduction and color development capabilities, and outstanding storage stability.   I. Core Industry Challenge: Why is the Stability of General Pigment Pastes Crucial? Modern industrial coating places extremely high demands on color consistency, coating durability, and production efficiency. A qualified general pigment paste not only needs to achieve high fineness and low viscosity during grinding but must also maintain stable performance after long-term storage, avoiding issues like inaccurate color matching, decreased film gloss, or surface defects due to pigment flocculation and thickening. Furthermore, with the advancement of environmental regulations, the application of high-solid and solvent-free systems is becoming increasingly widespread, posing more severe challenges to the compatibility of dispersants with resin systems and their stability under extreme conditions. Finding an additive that can provide stable dispersion effects across systems and pigment types is fundamental to enhancing overall formulation competitiveness.   II. Technical Core: The "Steric Hindrance" Stabilization Mechanism of 6062B The outstanding performance of ANJEKA-6062B stems from its scientific chemical design. As a block copolymer solution containing pigment-affinic groups, it functions through a unique "steric hindrance" stabilization mechanism: Anchoring and Extension: The pigment-affinic groups in its molecular chain firmly adsorb onto the pigment particle surface, while the polymer long chains fully extend in the solvent, forming a protective barrier. Preventing Flocculation: This barrier effectively prevents pigment particles from re-flocculating and aggregating as they approach each other due to Brownian motion, thereby achieving long-term stable dispersion of pigments. This mechanism brings multiple advantages: lower grinding viscosity (improving production efficiency and pigment loading), better color development (enhancing color saturation and hiding power), and stronger storage stability (resisting performance degradation caused by heat storage).   III. Empirical Performance: Application Feedback from Flooring and Industrial Coatings Laboratory data and customer applications jointly validate the comprehensive strength of 6062B: In the Epoxy Flooring Field: Comparative tests showed that white, black, and blue pastes prepared using 6062B had significantly lower initial viscosity than competing products, demonstrating excellent viscosity reduction. More importantly, their color development was visually superior (whiter, blacker, bluer), and after 7 days of heat storage at 60°C, the viscosity increase was slower, and fineness remained intact (≤30μm), ensuring batch-to-batch stability of the paste. In the final floor topcoat, whether for trowel or self-leveling applications, there was no joint color difference, and gloss was high. In the Industrial Coatings Field: 6062B demonstrated broad resin compatibility. In black and red paint tests in epoxy systems, after heat storage, not only did viscosity decrease, but color difference was minimal (ΔE

In the world of solvent-based coatings, achieving a vibrant, uniform, and stable color is a primary goal. However, a common yet often misunderstood phenomenon—pigment flocculation—can silently undermine this effort. Imagine a meticulously ground, fine pigment paste that, after storage, develops graininess, loses color strength, or causes floating and flooding. This is the work of flocculation. Unlike simple settling, flocculation involves the re-agglomeration of dispersed pigment particles into loose clusters, destroying the initial dispersion quality. This article delves into the root causes of flocculation in solvent-based systems and provides a systematic methodology for prevention, ensuring long-term color stability and performance.   Understanding the Mechanism – Why Do Pigments “Re-Clump”? In solvent-based coatings, the primary stabilization mechanism is steric hindrance, not electrostatic repulsion which dominates in aqueous systems. Here’s how flocculation occurs: Insufficient or Weak Anchoring: The dispersant molecule has a specific “anchor group” designed to adsorb firmly onto the pigment surface. If this adsorption is too weak, or if the dispersant dosage is insufficient to cover all pigment surfaces, the protective layer is incomplete. Exposed pigment sites become nucleation points for re-attraction via van der Waals forces . Poor Compatibility of the Solvated Chain: The “solvated chain” of the dispersant must be fully compatible with the resin and solvent system. If it is incompatible, the chain collapses rather than extending into the medium, drastically reducing the steric barrier. This allows particles to approach closely and flocculate. System Shock (Compatibility Issues): Even a stable pigment paste can flocculate when added to the final paint formulation if there is poor compatibility between the paste’s medium and the paint’s resins/solvents. This sudden change in environment can destabilize the dispersion .   The Flocculation Prevention Toolkit – A Four-Step Methodology Preventing flocculation is proactive, not reactive. Follow this systematic approach: Step 1: Select the Right Dispersant with a Strong “Anchor” The choice of dispersant is foundational. For solvent-based systems, high-molecular-weight polymeric dispersants that rely on robust steric hindrance are key. Match the Anchor to the Pigment: Different pigments (carbon black, organic red/yellow, inorganic iron oxides) have different surface chemistries. The dispersant’s anchor group must be tailored for strong, persistent adsorption. For instance, dispersing carbon black in a polyurethane system may require a different dispersant (e.g., Anjeka 6161A or 6881) than dispersing phthalocyanine blue . Prioritize Versatility for Complex Systems: If your formulation handles multiple pigments or resin systems, a versatile dispersant can simplify inventory and reduce compatibility risks. Products designed as “universal” for solvent-based systems (applicable in PU, epoxy, acrylic, etc.) offer a wider safety margin . Step 2: Optimize Dispersant Dosage – It’s a Science, Not a Guess Under-dosing is a direct path to flocculation. The dosage must be sufficient to achieve complete surface coverage. Follow Scientific Guidelines: A common starting point for polymeric dispersants is 10-50% on the weight of organic pigments/carbon black, and 2-10% for inorganic pigments. However, this must be validated for each specific case. Conduct a “Grind Curve” Test: Gradually increase the dispersant dosage in a series of lab grinds while monitoring fineness and viscosity. The optimal dosage is typically at the point where further addition yields minimal improvement in fineness or viscosity reduction. Insufficient dosage will lead to poor initial dispersion and guaranteed future flocculation. Step 3: Validate with Accelerated Stability Testing Initial fineness is meaningless without predicting long-term stability. Accelerated testing is your quality assurance. Standard Protocol: Subject the finished pigment paste or paint to heat aging (e.g., 50-60°C for 7-14 days). This accelerates the thermodynamic processes that cause flocculation during shelf life. Post-Test Evaluation: After heat aging, check for: Increase in Fineness Grind: Indicates particle re-agglomeration. Significant Viscosity Increase or Gelation: Can be a sign of flocculation or system incompatibility. Color Property Shifts: Check for loss of color strength, development of floating/flooding, or changes in gloss on drawdowns. Only a dispersant that passes this test can be considered effective for long-term stability . Step 4: Ensure Total System Compatibility The dispersant must be compatible with the entire formulation ecosystem. Resin and Solvent Compatibility: Verify that the dispersant’s solvated chain is compatible with your main resin (e.g., acrylic, PU, epoxy) and solvent blend. Incompatibility can cause haze, seeding, or viscosity instability. Pigment Paste & Final Paint Compatibility: When adding a resin-free pigment paste to the final paint, ensure it is added under steady agitation to facilitate smooth integration and prevent instant flocculation (“shock”) . Addressing Float/Flood: If flocculation manifests as floating or flooding (color separation), it may require a combined approach. Sometimes, a dispersant optimized for stabilization (e.g., Anjeka 6200C) may increase viscosity, while one good at reducing viscosity (e.g., 6111) may not prevent floating. In such cases, technical support may recommend a combination or a specific product like 6810 to balance both needs .   Partnering for Stable Color Preventing pigment flocculation is not about a single magic ingredient, but about a scientific selection process and rigorous validation. It requires understanding the interaction between the pigment, the dispersant’s molecular architecture, and the entire coating formulation.

In the world of composites, where extreme lightweighting and high performance are pursued, a barely visible "tiny bubble" can become the Achilles' heel of a product's performance. Whether it's hidden porosity inside a wind turbine blade or annoying pinholes on the surface of an automotive part, bubbles not only affect appearance but can severely compromise mechanical strength and durability. How to achieve "bubble-free" or "low-bubble" molding within high-viscosity resins, complex fillers, and demanding processes is a challenge every composite engineer must overcome.   I. Why Do Composites "Love" to Foam? – The Dual Challenge of Process and Material Composite manufacturing essentially involves physically mixing and chemically curing resins, fibers, fillers, etc., into a single entity. During this process, bubbles are almost omnipresent: Mechanical Introduction: High-speed mixing, filler addition, and incomplete vacuum infusion can all entrap air into the high-viscosity resin system. Chemical Reaction Generation: Certain curing reactions may produce gaseous by-products, which, if not released in time, form micro-bubbles. Surface Tension "Traps" Bubbles: The resin's own high viscosity and high surface tension make it difficult for entrained bubbles to naturally rise, merge, and rupture, forming a stable micro-bubble system. If these bubbles remain in the final product, they become stress concentration points, leading to premature failure under load or directly affecting the smoothness and protective properties of coatings. II. The "Methodology" of Defoaming: Not Just "Breaking," But Also "Preventing" Solving bubble problems in composites requires systematic thinking, not just remedial action at a single stage. An effective defoaming solution should address both: Rapid Bubble Breaking: Quickly reduce local surface tension during initial stages where many bubbles are generated (e.g., mixing), destroying the bubble film, causing them to merge, grow, and escape. Persistent Foam Suppression: Continuously inhibit the generation and stabilization of new bubbles during subsequent prolonged processes like resin impregnation of fibers and flow filling of molds, preventing secondary foaming. Compatibility and Stability: The defoamer itself must not react adversely with the system, causing craters, floating, or affecting resin curing and final performance. This is particularly important for transparent and light-colored products. This requires the defoamer to not only have efficient surface activity but also a delicate balance of compatibility with the complex composite system. III. Anjeka Solution: An Efficient Defoaming Partner Tailored for Composites Addressing the characteristics and process pain points of composite resin systems (such as epoxy, unsaturated polyester, vinyl ester), the Anjekang defoamer series aims to provide balanced solutions: For High Viscosity and Foam-Stable Systems: Its design can effectively penetrate and disrupt the foam-stable structure wrapped by the resin, promoting the merging and removal of fine bubbles, suitable for processes like hand lay-up and vacuum infusion. Focus on Broad Process Adaptability: Maintains defoaming and foam-suppressing efficacy under different shear and temperature conditions from initial resin mixing to mid-stage mold filling, compatible with various molding methods like hand lay-up, spray-up, pultrusion, and compression molding. Emphasis on System Compatibility: Through careful raw material selection and optimized formulation, it aims to minimize potential impact on product surface appearance (e.g., clarity of transparent FRP, gloss of gel coat) and physical properties. Engineers can select suitable models and conduct small-scale verification based on specific resin type, filler种类, process conditions, and transparency requirements, using the defoamer as a "key" to optimize processes and improve yield. IV. Application Implementation Suggestions: How to Use Defoamers Effectively? Diagnose First, Then Treat: Identifying whether the main source of bubbles is mechanical mixing, filler introduction, or reaction generation helps determine the optimal timing for defoamer addition (e.g., during initial mixing or before filler addition). Small-Scale Testing is Key: Before mass production,must conduct laboratory-scale tests to evaluate defoaming efficiency, compatibility, and effects on curing speed, final appearance, and performance. Follow Recommended Addition Methods: Ensure the defoamer is evenly dispersed in the system to avoid local overdosing. It is generally recommended to add it during the resin mixing stage with sufficient dispersion time. Systematic Coordination with Process: Defoamers are important auxiliary tools, but they must be combined with reasonable process parameters like vacuum degassing and appropriate curing procedures to achieve the best results.   Though small, bubbles are crucial to success.
