Product Description
R Chem Add Disperse - Lis an opacifying pigment that partially replaces Titanium dioxide. The white inorganic pigment lithopone (R Chem Add Disperse-L) is mostly made up of zinc sulphide (ZnS) and barium sulphate (BaSO4). It is perfect for the rubber, plastics, and coatings sectors because of its exceptional opacity, brightness, and UV resistance. Dispersion technologies are frequently used in the formulation to guarantee consistent texture and improved performance. It needs precise equipment to obtain the best dispersion when processed in ball mills or high-speed mixers. Lithopone comes in moisture-resistant bags and has a two to three year shelf life. Widely used in the paint, construction, and automotive industries, it improves the longevity and visual attractiveness of items.
