Barium sulphate, barite – it is a mineral with the high content of BaSO4.

It is distinguished for its high resistance against chemicals, for its high specific gravity the untreated types are mainly used in drilling industry as flushing medium, basic types are used for production of barite salts – lithopone, blanc fix, etc., treated milled and bleached types are used mainly as a filler for the production of paints, rubber, floorings, mastics…

Mixtures of barium sulphates and zinc sulphate (ZnS) are called lithopone.

Lithopone is a white pigment composed of ZnS and BaSO4. The lithopone gained its characteristics of pigment from ZnS thanks to increased refraction (2,37) while BaSO4 acts as a substratum.

With regard to very good dispersion, high whiteness, optimal granulometry and also for economic reasons (lithopone is in comparison with the titanium dioxide and other pigment disproportionaly cheaper) it is used for chromatosis of all paint systems, plastics, rubber and mastics etc.

 Calcium carbonate filler Omyacarb is pure white marble powder gained by crushing, milling and sorting of natural crystallic lime stone.

It is used for production of paints, mastics, rubber and plastic mixtures, construction materials, dispersive and mineral plasters, fine ceramics, etc.

Wide assortment of cost effective organic pigments. For the choice of suitable type it is necessary to know the application and required resistance – i. e. light resistance, thermal endurance, chemical stability, resistance against solvents. We will be glad to advise you with the choice of suitable type.
