Technology
We specialise in the manufacture surface treatment of synthetic barium sulfate and natural barium sulphate offering a range of products graded according to raw material source and particle size, down to 0.2 microns sub-micron grain size.
Baryte Powder
They offer formulators high whiteness and chemical inertness, making them ideal for powder coatings, industrial coatings and primer applications, where their inertness is useful under industrial or corrosive environments.
