What Are Industrial Coatings?

Coatings and industrial finishes are a type of paint that is chemically engineered to protect industrial products, like field-erected tanks and pipelines, from harsh environmental conditions and workplace abrasion.

Industrial paints are also used to line the inside of water reservoirs and tanks, protecting against corrosion and creating a safe environment for potable water.

Applications may require multiple layers of coatings, for example, a layer of primer, a layer of paint, and then a sealant. Industrial applications may also require coatings that are not only protective but also aesthetic — as is the case with many water standpipes and reservoirs.

Different Types of Industrial Coatings

There are many different types of industrial coatings. The primer, coating, or sealant that is ideal for your project depends on the environment your application is going to be placed in, the type of product you’ll be storing, and other factors.

Here is a brief introduction to some of the most common industrial coatings in the metal fabrication industry:

100% Polyurethane Coatings

Polyurethane industrial paint coatings excel at abrasion resistance and are used to protect applications against harsh environmental conditions and wear and tear.

Aromatic polyurethanes are used for steel parts that will be submerged in water but are less common in potable water tanks.

Here at T BAILEY, INC., we apply polyurethane coatings with plural component pumps. Instead of just mixing the coating, these pumps also heat it, which helps the coating cure much quicker. One practical effect of this is that parts can be moved in 1 hour, instead of having to wait 4-12 hrs before moving.

Epoxy Coatings

Epoxy coatings effectively resist corrosion, abrasion, and weathering, making them ideal for steel applications placed in harsh operating environments.

These coatings are also resistant to extremely high temperatures, so can be used on tanks that store hot product or are exposed to extreme heat.

One disadvantage of epoxies is that they chalk when exposed to sunlight. This is why epoxies are most often used in submerged or interior applications.

Industrial epoxy coatings are often applied in three layers. First, a primer is applied, like a zinc primer. Then the epoxy is sprayed on. Finally, an epoxy binder or polyurethane topcoat is applied to finish the coating process.

Zinc-Rich Coatings

Zinc coatings provide a polymeric and galvanic barrier, making them extremely effective for steel parts that require correction and abrasion resistance.

This robust protection comes from the zinc dust used in the coating, as well as the polyurethane or epoxy binders used to create the coating.

Acrylic Coatings

Acrylic industrial protective coatings are most commonly used on automotive and architectural applications due to their corrosion resistance and high-gloss characteristics. Acrylic coatings are less common for other industrial applications like tanks, reservoirs, and penstock.

Metalized Coatings

Metalizing is the process of melting down metal wire, atomizing the molten material, and then spraying it onto a product’s surface to create a strong coating.

This heavy-duty coating type can be formed using bronze, aluminum, nickel, chrome, stainless steel, zinc, and tungsten. Also, metalized parts are typically seal-coated to increase their corrosion resistance.

Here at T BAILEY, INC., we also have the capability to apply a non-skid walking surface via metalization.
