General Description:
ANJEKA-6502 is a copolymer solution containing acidic groups, designed as a dispersant suitable for solvent-based/UV system coatings and ink systems. It is well-suited for the dispersion of matting agents and inorganic pigments.
Product Data:
Chemical Composition: Copolymer solution containing acidic groups.
The data provided on this sheet represents typical values and not the technical specifications of the product.
Appearance: | Light yellow fluid |
Acid Value (mgKOH/g): | 120-170 |
Density (g/cm³ at 23℃): | 1.05-1.14 |
Viscosity (cps at 25℃): | 300-900 |
Non-volatile content %: | 98 |
Storage and Transport:
Before use, thoroughly stir the product, as layering or oiliness may occur at temperatures below 10℃. Heat to 30℃—40℃ and stir evenly. Storage time is not recommended to exceed 12 months.
Special Notes:
Due to the product's high acid value, it may catalyze the cross-linking of baking paint systems. Check for viscosity increases during the coating system storage process.
Application Instructions:
Properties and Benefits:
This additive utilizes spatial hindrance to disperse pigment clusters and uphold stability. The resultant fine particle size of dispersed pigment particles lends a refined appearance to numerous matte ink systems, preventing blooming. This augments the gloss, color vibrancy, and translucency of coatings. The additive notably diminishes viscosity, thus enhancing flow properties and accommodating increased incorporation of matting agents. In applications involving high-speed electrostatic rotary coating with inorganic pigments, it substantially diminishes overspray.
Application Fields:
Recommended for incorporation into solvent-based and solvent-free coatings, as well as printing inks, for the stabilization of inorganic pigments, particularly titanium dioxide. Thanks to its anionic attributes, this additive stands out as an excellent option for acid-catalyzed systems, such as coil coatings.
Recommended Levels:
Additive levels (as purchased) based on pigment:
Matting Agents: | 10%—50% |
Inorganic Pigments: | 1%—6% |
The above data represents empirical levels; the optimal dosage should be determined through a series of experiments.
Processing Instructions:
For optimal performance, add the additive to the grinding media first, then introduce pigments.
Packaging:
25kg internally coated iron drum
200kg ring plastic drum
