Description
Industrial Paint
Industrial paint refers to a protective coating system designed for industrial surfaces exposed to moisture, chemicals, abrasion, corrosion, weather and regular operational conditions. The right system helps protect steel, concrete and other suitable substrates while improving surface durability.
Protect More Than Appearance
Industrial paint is not simply selected by colour. Surface condition, corrosion level, substrate type and exposure conditions determine the correct primer, intermediate coat and topcoat system.
What Is Industrial Paint?
Industrial paint is defined as a protective coating used on industrial equipment, structures and surfaces.
It is formulated to provide specific performance properties beyond decoration. Depending on the system, these properties may include corrosion resistance, chemical resistance, moisture protection, abrasion resistance and weather resistance.
A complete industrial coating system may include surface preparation, a compatible primer, one or more intermediate coats and a finishing topcoat. Each layer has a different role in the protection system.
