Basic Components of Paints & Coatings
Paint formulation brings together four main groups of ingredients: pigments, binders, solvents and additives. Their balance depends on the substrate, application method and required finish.
Pigments
Pigments provide colour and hiding power and help control the appearance of the finished coating. Formulations may combine colour pigments with mineral extenders.
Binders
The binder forms the film and holds pigments together on the surface. Binder selection affects adhesion, durability and resistance to water, chemicals and abrasion.
Solvents and water
The liquid carrier helps distribute ingredients and adjust application viscosity. It leaves the film during drying; the appropriate carrier depends on the binder system.
Additives
Small additions can influence processing, storage stability and application. Silica-based additives may support matting, rheology control and resistance to settling. Selection requires testing in the complete formulation.
Selecting a silica additive
Start with your binder, substrate, desired gloss and application method. Review the technical data sheet and validate dispersion, dosage and final coating performance.
