Replace part of superfine aluminum Titanium dioxide is widely used in the paint industry at home and abroad technology has obvious economic benefits. Here for you to explain ultrafine aluminum silicate in the coating played some role:
1, to improve the whiteness of paint.
Ultrafine titanium silicate replace part of, not only does not change the titanium dioxide dry hiding power, but also improve the whiteness of paint. If the same amount of titanium dioxide, which will significantly improve the dry hiding power and whiteness large amplitude will increase.
2, the role of a buffer PH value.
PH value range of ultra-fine Aluminum Alloys silicate 9.7-10.8, with PH value buffer. In particular, vinyl acetate latex storage process, to prevent the hydrolysis of vinyl acetate leaving the PH value decreased, thus increasing the dispersion stability of the paint, while avoiding the inner wall of the metal container to corrode.
3, the paint has a good suspension.
Ultra-fine aluminum silicate, the grid structure makes the paint system is slightly thickened, with good suspension, and prevent solids sink to the bottom and surface water separation phenomenon.
4, enhanced paint scrub resistance, weather resistance.
Ultrafine aluminum silicate paint film that has a good scrub resistance, weather resistance, but also shorten dry time.
5, with a matting effect.
Ultra-fine aluminum with matting effect, so the semi-gloss, matt paint may be used as a matting agent economy, should not be used in the light paints.
