Application：Micronized barium sulfate is widely used as body paint in the paint industry such as topcoat, ready mixed paint, powder coating, high solid coatings, printing ink, latex paint and all kinds of industrial paints. In addition, it can be used as functional filler in plastics, ceramics, friction materials, anti-radiation materials and rubber products.
Packing: In 25kg or 50kg woven bag with plastic liner inside, or paper bag shrink wrapped on pallet, or as per buyer’s option.
