Functional Silica Additive for Coatings, Inks & Adhesives
Product Name:
Functional Silica Additive (for Coatings, Inks & Adhesives)
Description:
Our functional silica additive is a high-performance, micronized white powder engineered to enhance the rheology, stability, surface quality, and workability of coatings, printing inks, and adhesive systems. It improves anti-settling behavior, prevents syneresis, and optimizes application properties such as flow, leveling, and matting.
The additive is compatible with water-based, solvent-based, and UV-curable systems, making it suitable for a wide range of industrial and decorative formulations.
- Rheology and viscosity control
