Micronized Amorphous Silica Gel Paint Matting Agent Used For General Coatings
Description
1, Silicon Matting Agent is a syntetic, micronized amorphous silica gel having porosity and high purity. The chemical structure of this product is based on Silicon Dioxide (SiO2). Matting agents are used to reduce the gloss in a variety of coatings applications. The application segments for silica gel matting agents include wood furniture coating, industrial coating, coil coatings, automotive coatings and decorative coatings as well as printing inks, leather coatings and textile coatings
2, 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
| 1 Easy to Disperse: Advanced rubbing technology makes narrower distribution of diameter of granules, so that matting agent can be easily added in any production procedure and can be easily dispersed, which saves the processing time. |
| 2, 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. |
| 3, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index. |
