Precipitated Silica Matting Agent 7631-86-9 With Good Dispersibility
Description
It is a micronized synthetic amorphous precipitated silica dioxide appearing as white powder. This silica based matting agent for both solventbome and waterbome system. Optimal matting efficiency is achieved by using silica with high pore volume and by fine control of the particle size and particle size distribution. It provides a superior matting and flatting, excellent coating appearance and transparency, cost efficient, effective anti-settling agent and easy dispersion, smooth, abrasion resistant films of high surface quality. These efficient matting agent are suitable for unpigmented and pigmented systems. It mainly used for wood coating, decorative coating, industrial coating, plastic coating, coil coating and ink.
Characters
1, Good Transparency: Products high purity lead the refractive index inosculate with resin index.
2, Good Disperse Heat: Special production process to make heat quickly spread to other surfaces of paint, to extend the service life of paint.
3, 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.
4, Good Matting Efficiency: Advanced 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.
5, Good Dispersibility: This series of products that can easily decentralized in any paint system, the average high-speed pulsator with 10-20 M/S of the line speed, after 10 minutes can be ok.
