Matting Agent For Coatings
It is a synthetic amorphous silica appearing as white powder. It is a micronized precipitated silica matting agent for both solvent-based and waterbome system. Optimal 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. These efficient matting agent are suitable for unpigmented and pigmented systems. It mainly used for wood coating, decorative coating, industrial coating, plastic coating, coil coating and ink.
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,Excellent Transparency: The purity of SiO2 in these products reaches to 99.3%,and special method is adopted for surface treatment so that its refraction index reaches 1.47,being close to that of colophony,i.e. 1.40~1.60,which greatly improves its transparency in coating film and avoid the low-grade matt powder's problem of turning white and blue on the surface.
3, 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.
4, Excellent Hand-feeling: These silicas have minimal effect on the mechanical properties, allowing
development of smooth films with excellent hand-feel, scratch resistance and stain resistance.
5, Excellent Suspension Performance: This products have good anti-settling, suspension is good, no
