Mineral fillers for coatings and plastics
Six product families, from micronized grades to compounds made to customer specification.
6 products
BaSO₄
Micronized Barium Sulfate
A dense, chemically inert white filler with low oil absorption, used mainly in coatings.
Micronized gradesNatural Barite
Barite in its natural mineral form, used where density and chemical inertness matter more than fine particle size.
Natural mineralsCaCO₃
Micronized Calcium Carbonate
A widely used filler for paints, coatings and polymers. Particle size and distribution affect gloss, rheology and cost.
Micronized gradesKaolin
A platy aluminosilicate mineral used in some coating and polymer formulations for its effect on rheology, matting and film properties.
Natural mineralsSpecial Mineral Fillers

Choosing a mineral filler
Mineral fillers make up a large part of many paint, powder coating and plastics formulations. The right choice depends on the mineral, its particle size and distribution, its shape and its purity, and on what the formulation has to achieve.
Barium sulfate and barite are dense and chemically inert. Calcium carbonate is widely used as a functional extender. Kaolin has a platy shape that affects rheology and matting. When no standard grade fits, we develop a compound to the customer’s specification and test it in the formulation.
