Polyurethane Silica General Purpose Dispersant for UV Curable Printing

GENERAL DESCRIPTION

ANJEKA-6240 is a solvent-free wetting and dispersing agent designed for 100% solvent-free, solvent-based, and water-based UV-curable printing inks and coating systems. It exhibits high dispersing stability for organic pigments and carbon black, showcasing excellent viscosity reduction effects.

PRODUCT DATA

Chemical Composition: Copolymer with pigment-affinitive groups

The data provided on this sheet are typical values and not technical specifications.

STORAGE and TRANSPORT

Storage at temperatures below 0℃ may result in layering or oiliness; heat to 20℃ and mix thoroughly. Storage time is not recommended to exceed 12 months.

SPECIAL NOTES

Surface treatment of certain organic pigments may adversely affect the efficacy of this wetting and dispersing agent. In such cases, it is advisable to test with untreated pigments of the same type. When used in coil coatings, consider the interaction between this cationic additive and acid catalysts. Free acids or epoxy-closed acids are more suitable than amine-closed acids.

APPLICATION GUIDELINES

Industrial Coatings

Key Features and Benefits:

ANJEKA-6240 stands out for its well-balanced polarity and a formulation composed of 100% active ingredients. This results in exceptional stability in dispersing pigments across 100% solvent-free, solvent-based, and water-based UV-curable systems. Its superior performance is particularly evident in maintaining the dispersing stability of organic pigments and carbon black. During the dispersion process, ANJEKA-6240 not only achieves remarkable and efficient viscosity reduction but also eliminates thixotropic behavior.

The inclusion of ANJEKA-6240 in coating systems leads to a substantial improvement in extended storage stability. Its remarkable anti-flocculation characteristics make it an ideal selection for coatings that require heightened aesthetic performance. Noteworthy contributions include the enhancement of color strength, transparency, gloss, and the reduction of haze in the final product.
