How Anjeka-6810 Delivers "Smooth Flow" to Industrial Coatings

Breaking the "Grinding Bottleneck" in High-Solid Pigment Pastes: How Anjeka-6810 Delivers "Smooth Flow" to Industrial Coatings

In industrial coatings, automotive paints, and high-end inks, color is more than appearance — it's a declaration of performance and quality. Behind every vibrant finish, however, formulators face a persistent challenge: how to achieve low grinding viscosity and efficient production while maintaining excellent color development and stability in high-pigment-load pastes?

High grinding viscosity means not only higher energy consumption and longer production cycles — it can also trigger a cascade of issues including flooding, floating, and settling, directly impacting final film appearance and performance consistency. This has become an "invisible bottleneck" limiting efficiency and product quality in many coating operations.

The Limitations of Traditional Dispersants: The Anchoring-Stability Dilemma

Conventional dispersants often fall short when handling carbon black, phthalocyanine, and complex organic pigments. Their mechanisms may fail to form sufficiently strong and durable anchoring layers on difficult pigment surfaces, resulting in low dispersion efficiency and persistently high grinding viscosity. More critically, in multi-pigment systems, inadequately stabilized pigment particles re-flocculate and migrate — causing flooding and floating after storage or application, which frequently leads to customer complaints.

Anjeka-6810: A Block Copolymer Solution Based on CPT Technology

Understanding this pain point, the Anjeka technical team has developed Anjeka-6810 — a block copolymer dispersant designed using advanced CPT technology. This is not a simple surfactant, but a precision-engineered molecular structure that brings an innovative approach to pigment dispersion.

1. Strong Anchoring — Viscosity Reduction at the Source

Anjeka-6810's molecular segments include chains with excellent compatibility with various resin systems (epoxy, polyurethane, alkyd, etc.) and polar anchoring groups that strongly adsorb onto pigment surfaces. This structure ensures a firm, dense adsorption layer on the pigment surface. Through powerful steric hindrance effects, it fully deflocculates pigment particles and maintains them in a stable, separated state — significantly reducing internal friction within the grinding paste. Test data shows that in epoxy carbon black paste systems, 6810 delivers excellent initial viscosity and hot storage viscosity stability, paving the way for efficient grinding production.

2. Superior Color Development — Unleashing Pigment Performance

When pigment particles are fully deflocculated and stably dispersed, their original particle size is more perfectly realized, delivering:

• Significantly enhanced color strength: Brighter, more saturated colors at the same dosage.

• Optimized transparency or hiding power: Transparent pigments become clearer; opaque pigments offer stronger hiding power.

• Improved gloss: Smoother film surfaces yield superior optical effects.

3. Three-Dimensional Protection — Eliminating Flooding and Floating

The steric hindrance stabilization mechanism is not just about reducing initial viscosity — it provides long-term stability. In multi-pigment systems (e.g., grey paints), the migration tendency of different pigment particles — driven by differences in density and surface properties — is effectively inhibited. Anjeka-6810's steric protection barrier significantly reduces flooding and floating, ensuring color consistency from production through application, and enhancing end-user experience.

Why Is It Particularly Suitable for High-Solid Systems?

Anjeka-6810 features a 70% high-solid content design, closely aligned with the industry's trend toward high-solids, low-VOC formulations. It delivers excellent dispersion and stabilization performance even at high pigment concentrations — making it ideal for preparing universal pigment pastes or high-concentration grinding pastes, helping customers simplify processes and increase production capacity.

Seeing Is Believing — Validate Through Testing

We understand that a reliable test is worth more than any technical statement. Anjeka encourages and supports direct comparative validation:

• Method: Replace your existing dispersant with an equal amount (or recommended dosage) of Anjeka-6810 in your current formulation.

• Key focus areas: Compare grinding viscosity, time to reach target fineness, paste color development (rub-out test or panel comparison), and most critically, hot storage stability (viscosity change, coarsening, floating evaluation).

• Goal: Let the data speak — witness the viscosity reduction and stabilization performance in your specific system firsthand.

In an increasingly competitive market, improving product performance and production efficiency is an eternal theme. Anjeka-6810 dispersant is designed to provide formulators with a powerful tool — transforming the "grinding bottleneck" into a "smooth flow advantage" — helping companies create products with superior color, more stable performance, and greater production efficiency.
