Zinc white is produced in БЦ0 (zinc white of БЦ0 grade, obtained with the muffle method, is marked as БЦ0М) and БЦ1grades:
- product of БЦ0М grade is used for manufacture of the general mechanical rubber goods and tyres, paintwork materials, artificial leather and sole rubber, conductor cables, dental cement, abrasive wares for stomatology;
- product of БЦ1 grade is used for manufacture of the paintwork materials, asbestos technical products, artificial leather and sole rubber.
Zinc white grade А
They represent zinc oxide, obtained by means of sublimation and oxidation of metallic zinc and zinc-bearing wastes.
