10kg paper bag packing method of precipitation silica matting agent for paint use

Model Number: BT-30-1 Brand Name: BaoTe Key Specifications/Special Features: Good transparency: products high purity lead the refractive index inosculate with resin index.Good disperse heat: Special production process to make heat quickly spread to other surfaces of paint, to extend the service life of paint.Good suspension: This series of products the within molecular structure and surface structure have been a special treatment, place a long time don’t appear hard and stratified sedimentation phenomenon.Good matting efficiency: Advance production technology to make our products not only increase pore volume but also ensuring that the particle arrangement gap uniformity to achieve very good matting efficiency.Good dispersibility: The series of products that can easily decentralized in any paint system, the average high-speed pulsator with 10-20M/S of the line speed, after 10 minutes can be ok.
