Micronized Amorphous Silica Gel Paint Matting Agent Used For General Coatings
Description
Silicon Matting Agent usually used for general wood coatings, industrial coatings,
plastic coatings. 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 is go through our advanced crushing equipment for ultrafine grinding. It is a kind of virulent insipidity, nonflammable fluffy white powder, which is soluble in caustic soda and hydrofluoric acid only. Other characteristics are no decomposition, discoloration under high temperature, but with certain water imbibitions.
Characters
High Matting Effect. Careful design matting agent physical properties and the performance, high pore volume and fine controlled particle size and particle size distribution makes high matting efficiency.
