CP-APA Organic Clay for Paint
CP-APA Organic Clay for Paint
CP-APA is a kind of organo clay rheological additive. It is used in systems containing moderate to highly polar solvents (ketones, ester, ether esters, alcohols, aromatic).Powdered rheology additive derived from organophilic phyllosilicate, designed for polar to medium-polarity systems to provide thixotropic flow behavior.

Coatings Industry – Special Features and Benefits
Due to its unique organic modification, CP-APA is ideally suited to influence the flow behavior of polar- to medium-polarity coating systems. Using this additive produces thixotropic flow behavior, resulting in significant improvements in anti-sagging properties while maintaining good leveling. It also enhances storage stability and prevents pigments and fillers from settling.
Using of CP-APA Organic Clay for Paint
CP-APA can be added directly in powder. The addition is recommended to be before grinding procedure to get the best effectiveness. Addition level is commonly 0.2%~2.0%.
Powder Coatings – Special Features and Benefits
CP-APA is a rheology additive designed to increase melt viscosity in powder coatings. Even at low addition levels, it raises melt viscosity during extrusion and the cross-linking reaction. The resulting coatings show good leveling. At higher dosages, it creates a fine texture and lowers gloss. CP-APA can also adjust the surface structure in finely textured systems. Increased melt viscosity enhances edge coverage, contributing to improved anti-corrosive properties.
Recommended Use
The additive is suitable for powder coatings based on epoxy, polyester, polyurethane, and acrylate resins, as well as polyester/epoxy blends.
Recommended Levels
0.5–4% of the additive (as supplied) based on the total formulation. These levels are for guidance; the optimum dosage should be determined through application-specific testing.
Incorporation and Processing
Mix the additive with resin, hardener, pigments, and other raw materials using a high-speed mixer, then proceed with extrusion.
