Matting Agent for Leather Coating
1, extinction powder particle surface is not organic coating.
2, extinction powder easily dispersed in any leather coating, just use the general high-speed mixer can be used about 5 m / s perimeter speed of the paddle, the 15-20 minutes of mixing, you can achieve a good dispersion , Hegman fineness value of 15-25 microns.
3, if the long ball mill or three-roll mill for dispersion, may reduce the extinction effect and increase the viscosity.
4, silica extinction powder, slow down in the paint in the paint, the film surface when there are still many dry in the surface, the formation of small rugged, so that the incident into a diffuse scattered light reflection, gloss decreased, but not Affect the smoothness of the appearance of leather film and feel. Add extinction powder, the film fullness, anti-scratch, wear resistance, anti-deposition performance better.
