POR-15® Rust Preventive Coating is a non-porous coating that seals and protects many surfaces from water, chemicals, salt, and other corrosive contaminants. POR-15® Rust Preventive Coating is an effective anti-corrosive and rust preventive coating that offers superior chemical resistance due to its dense, cross linked molecular composition and nonporous attributes. It dries to a rock hard, non-porous finish that won't chip, crack, or peel, and it prevents rust from recurring by protecting metal from further exposure to moisture. POR-15® Rust Preventive Coating is sensitive to UV light and must be topcoated when prolonged exposure to sunlight is possible. Topcoating is not required for areas not exposed to sunlight.FeaturesSingle component permanent moisture cured urethaneNon-porous coatingChemical resistantSelf-leveling when applied with a brushProtects your investmentCompletely waterproofAbrasion chemical, stain and impact resistantEffectively adapts to the expansion and shrinkage of surface caused by temperature changesDoes not crack, chip, or peel from the surface substrateHammer toughExceeds 2000 hr salt spray testDries faster in humid conditions
