¢ñ .Benefits and Application
Calcine and classification ensures DB series without any coarse particle. Therefoue, DB series has low content of 325 mesh screen residue and always keeps high Hegman grind. DB series can be applied to latex paint, powder coating and fields.
Its main benefits are:
¡ô It's the best extender of titanium dioxide with excellent opacity that can improve efficiency and cut costs by partly replacing titanium dioxide.
¡ô It can easily disperse in water or oil base after highly micronixing trturating.
¡ô Superfine particle, excellent anti-settling property gives coating good tin opening effect.
¡ô Good inert to any acid and alkali in common temperature gives coating excellent corrosion stability.
