White Powder Silica Matting Agent Counter For UV70C Used For UV Coatings
Introductions
Silica Matting Agent good matting results have been obtained in UV-curing coatings using silica gel matting agents and careful formulation. Clear advantages were seen for surface-treated silica gel products of relatively low particle size. UV-cured lacquers and thermosetting powder coatings undergo minimal or no shrinkage during film formation.
Feature
1, Lower Viscosity. It has low oil absorption, good dispersibility, and excellent matting efficiency.
2, Surface smoothness. These silicas have minimal effect on the physical properties, allowing development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
3, Excellent Transparency. The refractive index of silica is comparable to most resin systems.
