Silicon Dioxide Matting Agent Used For PU/PVC Matte Finish Leather Coating
Description
| 1, Matting Agent specialized used for the PU/PVC matte finish leather coating. It provide a medium-high viscosity with a pleasant matte finish. They resist dripping and offer excellent adhesion and high flexibility with wet-dry abrasion resistance. |
| 2, Matting Agent is a synthetic amorphous silica appearing as white powder. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. 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. Optimal 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. |
Characters
| 1, High Transparency: Fine control of the particle size and particle size distribution, and gives better transparency for leather coating. |
| 2, Excellent Dispersion: The matting agent can easily disperse in both solvent and aqueous solution, the average high-speed pulsator with 10-20 M/S of the line speed, after 10 minutes can be ok. |
| 3, High Matting Efficiency: It can reduce the gloss for the surface of leather, provide the better matte finish. |
| 4,.Stable Chemical Property: As the matting agent is with high purity and low impurity, its chemical property is very stable. |
