Precipitated Silica CAS No.: 281122 Paint Matting Agent as White Powder Used For Industrial Coatings
Introductions
Matting Agent specialized used for the Industrial coatings. It is synthetic amorphous silica appearing as white powder. It is a micronized precipitated silica matting agent for both solvent-based and water-based system.
Feature
1) High Matting Efficiency: High pore volume reaches to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution.
2) Easy to Dispersion: The matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time.
3)Good handing feeling and improvement in scratch resistance: It is development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
