Its main benefits are:
Itf+s the best extender of titanium dioxide with excellent opacity that can improve efficiency and cut costs by partly replacing titanium dioxide;
It can easily disperse in water based systems;
It offers superfine particle and with excellent anti-settling property;
It is inert to most acids and alkaline at ambient temperature and offers good anticorrosive capabilities.
