Other characteristics |
The specific high whiteness, pigment non-precipitating and dispersing capability of MICROBARI® high bright barium sulphate make it unique from other traditional filler. Besides, high bright barium sulphate has low absorption of oil, which can increase the critical pigment volume concentration of coating and reduce the use of resin basic materials accordingly. MICROBARI® high bright barium sulphate of relative low price can replace expansive TiO2 partially, and effectively reduce the cost of coating products. So, the choice of MICROBARI® high bright barium sulphate can not only improve the quality of products but also reduce the cost of production.
