4 Types of Industrial Paint Coatings

Industrial paint is defined by the protective layer it offers, rather than its aesthetic properties. Industrial paint is commonly used to protect steel structures such as bridges and pipelines from corrosion. It also offers intumescent coating to protect structures from fire.

Most commonly used polymers in industrial coatings are epoxy, polyurethane, fluoropolymer, and moisture-cure urethane. Other industrial coatings include phosphate, Xylan, and PVD coatings. A normal coating system may include a primer, an intermediate coat and a top coat. The polymer film created a physical barrier between corrosive environment and steel substrate. Different types of coating are used in different environments.

Classification of Paints

Primers

Primers are applied directly onto the cleaned surface of steel. The main purpose of primers is to wet the surface in order to provide excellent grip for subsequently applied coatings.

Intermediate coats

These coats are applied to build thickness. Usually, the thicker the coating the longer the life. They are designed to improve the protection and when highly pigmented, reduces permeability to to water as well as oxygen.

Finish coats

Finish coat gives the structure required appearance. It provides defence against open exposure, and weather & sunlight.

Stripe coats

They are extra coats of paint that are used for fasteners and other external corners of the structure. Their main job is to create a satisfactory coating thickness at corners and edges where paint usually contracts and gets thinner upon drying.

  1. Wow, I had no idea that there would be so many different types of paint! However, I imagine that all four of these coats are absolutely necessary, especially if they are applied to a piece of industrial equipment. After all, chipped and faded paint is a sign of something being old, which is not what you want.
