Mastic-Lok AF is a versatile, high build, 100% solid, and VOC compliant mastic epoxy polyamide primer with aluminum flake that works even in the harshest of environments. It can be applied on marginally prepared substrates with outstanding adhesion to metal surfaces and most existing coatings. Mastic-Lok AF withstands severe weather conditions, corrosion, moisture penetration, and highly corrosive environments. This primer can be used to refinish aluminum before adding a topcoat, and wets and penetrates firm rust and tight crevices. It will resist further rust deterioration even in the most extreme corrosive environments due to the aluminum flake.
