Product description

Size:1 quart  |  Color:Gray

POR-15 Rust Preventive Coating is the Only Product that REALLY Stops Rust Permanently! POR-15 Rust Preventive Coating is designed for application directly on prepped rusted, sandblasted, and seasoned metal surfaces. 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 top coated when prolonged exposure to sunlight is possible. Top coating is not required for areas not exposed to sunlight.


From the manufacturer

* LABORATORY TEST RESULTS

POR-15 Rust Preventive Coating was tested for 168 hours at 97°F in a condensing humidity salt spray (ASTM B117). At the end of the test period, coated steel was free of rust or pitting. Acid and alkali resistance tests performed found panels coated with POR-15 Rust Preventive Coating to be impervious to gasoline, oil, chromic acid, hydrochloric acid, phosphoric acid, sodium hydroxide, caustic soda, 50% sulfuric acid, and 50% hydrofluoric acid. POR-15 Rust Preventive Coating was applied over a rusty substrate as a finish coat (approximately 23 mils dry film thickness). The coating showed essentially no undercutting at the scribed area after 2000 hours in a weatherometer*.

A 2 mil thickness of POR-15 Rust Preventive Coating was applied to lightly rusted steel and then exposed for 1000 hours to a salt spray. At the end of the test period, no undercutting was observed at the scribed area. Recoatability is excellent. Laboratory tests have shown very good adhesion when applied up to 14 days after application of the first coat. In an actual Field test, a topcoat was applied 6 weeks after the first coat had been applied, and the intercoat adhesion was excellent as determined by a crosshatch tape test. A metal box used as a filter for raw sewage was coated with POR-15 Rust Preventive Coating and placed in service within a few hours after the interior and exterior were coated. No visible rusting occurred at the welded areas after a six month exposure.

A POR-15 Rust Preventive Coating coating was subjected to 450°F for 10 hours; it remained hard and showed no apparent loss of adhesion. A panel subjected to elongation was pulled beyond the yield point of the base metal without affecting the POR-15 Rust Preventive Coating coating.
