Silicon Dioxide Paint Matting Agent Used For Leather Coatings
Introductions
Matting Agent specialized used for the PU/PVC matte finish leather coating. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. The special Paint Matting Agent can be applied to different resin systems.
It can be not only improve the haze of leather coating, but also the Original color of the coating. In focal system, it shows beautiful white degree, after polishing transparent feeling strong, treatment against with color more vivid. It also features good leveling property, and will not produce agglomerate or precipitation.
Feature
1, Easy to Disperse. The matting agent can easily disperse in both solvent and aqueous solution.
2, High Matting Efficiency: It can reduce the gloss for the surface of leather, provide the better matte finish.
3, High Transparency: Fine control of the particle size and particle size distribution, and gives better transparency for leather coating.
4, Excellent hand feeling.
