Primers (key coats) are designed to provide adequate adhesion between the surface and subsequent topcoats. Primer equalizes the absorption of the surface, binds dust particles that cannot be removed by cleaning, and improves adhesion. It can also harden the surface. Primers are not independent coatings; they are always used as a first coating in the coating system.
