Ultra-fine Modified Precipitated Barium Sulfate for Matt Powder Coating


Product Name: Ultra-fine Modified Precipitated Barium Sulfate for Matt Powder Coating
Properties: 
1.Brighter color: Extinction Barium has a very good dispersity,soit bring the hiding power into full play.As the carrier of pigments,it makes the pigments disperse more effectively and get a level and sterling color.Its high-purity whiteness makes the color tone brighter and purer;its ultra-fine crystal structure and high refractive index make color fuller.  
2.More steady system: Because of its chemicdl inertness,the system can keep Stable.And because of its ultra-fine particle size and high surface tension, it can suspend very steady in system and do not flocculate and deposit. 
3.Firmer Lacquer film: Because of its high density, it has a very good wear Resistance.And because of its equal particle size,it makes paint film more Level ansd smooth,more durable and firmer. 
4.Better Weather Resistance: Extinction Barium is chemical inactive,so it has the characters of water resistance and acid resistance,and also,it can endure high temperature and resist acid rain corrosion.Furthermore it has the function of absorbing ultraviolet radiation,which improves coating is weather resistance. 
5.More economical: Extinction Barium has not only high-whiteness but also excellent hiding power and dispersity.Therefore,it can decrease the dosage of titanium dioxide and reduce cost at the same time that improve quality. Extinction Barium is oil absorption is very low,so it can save the resin during the course of usage.Thus Extinction Barium is a kind of economical material.
