POR-15 Rust Preventive Coating
Use as part of the POR-15 3-Step System for Permanent results
The ultimate rust preventive system for permanent corrosion protection. Shields metal in just 3 easy steps, clean it, prep it, and coat it.
- Step 1: POR-15 Cleaner Degreaser removes grease, oil, dirt & grime in one application without leaving residues, or flammable solvents.
- Step 2: POR-15 Metal Prep provides the best adhesion for POR-15 Rust Preventive Coating on any metal surface.
- Step 3: POR-15 Rust Preventive Coating is a high performance coating designed for application directly on stable rust or seasoned metal surfaces.
POR-15 Rust Preventive Coating
Stop Rust and Corrosion Permanently
POR-15 Rust Preventive Coating 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.
Provides rust protection with a hammer-tough finish.
- Seals rust permanently
- No need to remove rust before applying
- For metal substrates
- * Exceeds 2000 hour salt spray test
- * Tested over 450°F / 232°C
- Repels fuels and oils
- * Resistant to most acids and alkalis
Proper application of POR-15 Rust Preventive Coating using the 3-Step System
Step 1: Clean it!
Remove loose rust and degrease surface with water-based POR-15 Cleaner Degreaser
Step 2: Prep it!
Neutralize rust and etch it with POR-15 Metal Prep. Thoroughly wash with water and dry.
Step 3: Coat it!
When surface is dry, apply POR-15 Rust Preventive Coating right onto the rust with two or three thin coats!
For areas exposed to U.V. light – Topcoat it
Topcoat with POR-15 Top Coat, POR-15 2K Urethane, or other top coat of your choice. Top Coat the POR-15 Rust preventive while it is tacky for proper adhesion.
* 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.
