Industrial Paints
Mineral fillers for the application and film requirements of industrial paints.
Overview
Industrial paints protect and finish metal, wood and other substrates in manufacturing. Their formulations have to meet application, drying and durability requirements at an acceptable cost.
Mineral fillers affect these requirements through their particle size, shape, density and chemical behavior.
Formulation challenges
- Application properties
- Viscosity, sag resistance and flow depend partly on the type and fineness of the fillers.
- Film properties
- Hardness, sanding behavior and appearance are influenced by filler selection and loading.
- Consistency
- Batch-to-batch uniformity of the filler supports consistent paint production.
The role of mineral fillers
- Functional fillers
- Barium sulfate, calcium carbonate and kaolin each bring different properties to an industrial paint.
- Particle size control
- The particle size distribution affects fineness of grind, appearance and cost.
- Formulation cost
- Some fillers can partly replace more expensive raw materials.
Applicable 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 mineralsCustomized Mineral Compounds
Blends of minerals designed around a customer’s formulation requirements.
