Epoxy Coatings

---

Epoxy coatings are created by combining an amine curing agent with an epoxy polymer, similar to the 

two-part epoxy adhesives used for creating strong bonds between materials. By adjusting the mix ratios and ingredients, formulators can develop epoxies with specific properties to meet various project requirements.

Epoxy coatings are highly adhesive to numerous surfaces and can endure harsh environments and abrasion. They are particularly effective against high temperatures, with some formulations capable of withstanding up to 1,400 degrees Fahrenheit.

Contractors typically apply epoxy coatings in two- or three-part systems. For optimal corrosion protection, an epoxy coating over a zinc primer serves as an excellent base. In a three-part system that includes a zinc primer, an epoxy binder, and a topcoat, a polyurethane topcoat might be recommended for improved aesthetics and superior performance.

However, epoxies do not perform well under sunlight exposure. Similar to aromatic polyurethane, they are better suited for submerged surfaces or components that are not exposed to direct sunlight. Examples of structures that benefit from epoxy coatings include interior steel tanks in nuclear power plants and submerged pipes in water treatment facilities.
