Two-Compartment Coating

Definition - What does Two-Compartment Coating mean?

A two-compartment coating refers to cross-linking resin systems that must be stored in separate containers prior to use because they are highly reactive with one another. The resulting product from such a reaction is an epoxy compound that is applied to a metal's surface as a protective film.

Corrosionpedia explains Two-Compartment Coating

Two-compartment coatings are applied with a spray gun that has container fittings for two separate feed lines. An example of a resin pair that is typically applied using a two-compartment spray gun is a polyester gel-coating.
