Wood coating technology silica matting agent white powder
Description
Silica Matting Agent is is based on Silicon Dioxide (SiO2), micronized amorphous silica gel having porosity and high purity. The chemical structure of this product Matting agents are used to reduce the gloss in a variety of coatings applications. The general process is to attain silicate liquid by the acid neutralization reaction of sodium silicate solution, then processing it with filtering, washing, drying, finally let it go through our advanced crushing equipment for ultrafine grinding.
Characters
1.Good extinction efficiency:Advanced production technology enables our products not only to increase the porosity, but also to ensure the uniformity of particle alignment gap, which can achieve very good extinction efficiency.
2.Good transparency: The high purity of our products ensures that the refractive index can match the refractive index of resin.
3.Good heat dissipation: the special production process allows the heat to spread quickly to other surfaces of the paint, thus extending the service life of the paint.
