Silicon Dioxide High Matting Efficiency Paint Matting Agent Used For PU Wood Coatings
Description
| 1, Polyurethane wood coatings have excellent versatility and exceptional chemical and physical resistance. Polyurethane coatings for wood applications are available for one-component (1K) or two-component (2K) solventborne or waterborne systems. Polyurethane wood coatings provide a flexible, functional and aesthetic solution to preserve and protect wood’s natural beauty. |
| 2 ,Silica matting agent generally used for PU wood coating. 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, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index. |
| 3, Good Dispersion: 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, 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. |
