High Matting Efficiency Counter For OK412 Silica Matting Agent Used For Auto-Motive Coatings


Silica Matting Agent usually used for the Automotive Coatings. Automotive Coatings is paint used on automobiles for both protection, decoration and refinish purposes. Automotive Coatings enhance the appearance and also protect it from extreme temperature, UV radiation, and foreign particles. Matte Finish is a low profile, non reflective finish that delivers superior coverage. Ideal for painting racing stripes or entire hoods in a matte black finish. Also great for grills, spoilers and other accessories.


1, Super Matting Efficiency. The high purity silica and 1.8-2.0 ml/g Pore Volume as well as fine control of particle size and particle size distribution, it makes the paint film higher matting efficiency.

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.
