Silica Matting Agent Silica Flatting Agent
◆Description of products
Silica matting agent is often used in the top(surface)
of the paint film coating , the extinction principle can be summed up in two kinds : one is to increase the roughness on coating surface, the second is to reduce the intensity of reflection light of substrate. Since 2000 year, our company began to produce silicon dioxide (Silica Matting Agent), it had been 13 years experience till now.
Since started producing low silica matting agent in the early of our company establishment, we strengthen research and development team continuously in the past 13 years. The sales of precipitated silica matting agent reached 1500 tons and the aerogel silica matting agent reached 2000 tons in 2013.
Furniture painting, decoration paint. Leather paint, plastic paint,ink ,water-based paint.
