Paint Matting Agent CAS No.: 7631-86-9 Used For Wood Matte Varnish
Description
1, Wood Finish matte is typically used reduce the Gloss of Wood Finish. It is Suitable for both interior and exterior woods, this low gloss, matte finish varnish contains UV absorbers to provide long lasting, beautiful rich protection.
2. Silica Matting Agent popular used for Wood Matte Varnish. It is synthetic amorphous micronized precipitated silica appearing as white powder and for both solvent-based and water-based system. Advanced 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. Silica Matting Agent reduce the gloss of a variety of products including coatings, paints, inks, lacquers, varnishes, while providing lower viscosity and better flow capability.
Characters
| 1, Highest matting efficiency: High pore volume reach to 1.8-2.0 ml/g, and fine control of the particle size and particle size distribution. |
| 2, Surface smoothness and improvement in scratch resistance: These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance. |
| 3, 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. |
| 4, Excellent Transparency: Products high purity lead the refractive index inosculate with resin index. |
