Natural Barium Sulphate

The products in the paint and coatin:Paint does not only beautify our environment, it also protects our valuable resources against destruction and decay. We supply a wide range of barites for this application. In the paint and coating industry. We have adoped a philosophy of supplying consistent high quality products at very competitive price.

Hiding Power of Pigment:The ability of paint to hide the colours beneath is dependent largely on the number and size of pigment particles per unit area:also, on their light absorbing and light scattering capacity.

If a paint layer has no pigment particles in it, its hiding power depends on the absorption and scattering of light by the vehicle. But if the layer has many particles per unit area, each layer will have considerable hiding power. For light coloured layers, the pigments must have a high capacity to scattering property of pigment depends on the ratio pigment to vehicle of refractive index. it is important to have pigments with indices of refraction as different as possible form the vehicle.

Oil Absorption:Oil absorption is a property important to paint formulators, rubber compounder and plastics companies. It often determines the amount of resin, binder or solvent required in a particular formula

Factors in Paint:The technical properties of these pigments depend only their chemical composition or their crystlline structure. but also on their particle size distribution and whether and inorganic or organic surface coating has also been applied to them. The optical properties of white pigments in medium such as a paint are mainly characterized by two factors: their absorption of light and, particularly, their ability to scatter light.

PH Value:This property is important in light of the fact that most liquid systerms(where barite is used as functional filler or pigment extender) will be influenced by acidic or basic chemicals. Undesirable effects from poor pH balance in paint systems are:
