SILCA MATTING AGENT USE FOR PAINTS/COATINGS
Description
It is a synthetic amorphous silica appearing as white powder as Paint Silica Matting Agent.
Characters
Good transparency: | High purity of our products ensures that refractive index can inosculate with resin index. | ||
Good disperse heat: | Special production process makes heat quickly spread to other surfaces of paint so that service life of paint can be extended. | ||
Good suspension: | Inner molecular structure and surface structure have been specially treated so that hard and stratified sedimentation phenomenon cannot form from even though it is placed somewhere for long time. | ||
Good matting efficiency: | Advanced production technology makes our products not only increase pore wolime but also ensures that the particle arrangement gap uniformity can achieve very good matting efficiency. | ||
Good dispersibility: | This series of products can easily be decentralized in any paint system,stirring of average high-speed pulsator with 10-20M/s of the line speed for 10 minutes can get very good effect. |
