High Purity Aerosil Fumed Silica , Solvent Based Flattening Agent For Paint

High Purity Silica Matting Agent Counter For C907 Used For Industrial Coatings

Description

Silica Matting Agent specialized used for the Industrial coatings. It is a micronized precipitated silica matting agent for both solvent-based and water-based system. These efficient matting agent are suitable for unpigmented and pigmented systems. Careful design and control of silica physical properties ensure dispersion stability, hand-feel, anti-setting behavior and scratch resistance in solvent-borne and water-borne system.

Characters

1, High Matting Efficiency: As this high-grade matt powder improves its porosity to 1.8-2.0 and decreases the distribution of micropores and ultra-large pore, the distribution of pores is more symmetrical and greatly improves the efficiency of delusterant; the diameter is narrower so as to reduce the negative influence of small granules on the effect.

2, Easy to Disperse: 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.

3, Excellent transparency: High purity of silica product ensures that refractive index can inosculate with resin index.
