POR-15
is easier and less expensive to apply than epoxies, since it doesn’t require
mixing: and POR-15 dries to a high-gloss or semi-gloss finish
like paint, except that it cannot he scratched or peeled off.
GENERAL INFORMATION POR-15® is a paint-like substance which acts as a total rust inhibitor and also very effective as a metal filler. Its consistency is approximately that of paint and it has very good spreadability (one quart covers 96 square feet). POR-15® chemically bonds to rusted steel to form a rock-hard, nonporous coating that won't crack, chip, or peel. It works by isolating metal from moisture; without moisture present, steel can’t rust. Thin, covering coats are best. Apply second coat when first coat is dry to touch with slight "finger-drag" remaining. APPLICATION OF POR-15® TO NEW METAL For proper adhesion to aluminum, galvanized metal, and smooth steel surfaces, prep with POR-15® Prep & Ready™ Rust Remover/PrePrimer. Keep surface wet for 15 minutes, then rinse off with water and dry thoroughly. This process will leave a zinc phosphate coating on the metal and insure perfect adhesion. ULTRA-VIOLET SENSITIVITY POR-15® is sensitive to UV light (sun) and must be topcoated for prolonged exposure to sunlight. Failure to do this may result in long-term damage to the POR-15® coating. Topcoating is not required for areas not exposed to sunlight. WHICH FORMULA TO USE?
Appearance: Glossy or Semi-gloss (black only) finish. Application: Brush, roller, spray Spreadability: 96 sq. ft. per Quart, 384 so. ft. per gallon. Recommended Temperature Application: 45°F - 95°F Drying Time: Varies according to humidity; average is 4.5 hours. Shelf Life: Unopened can - 2 years or more. Opened can - up to 6 months. Abrasion Resistance: Using Taber Abrasion Test, POR-15® passes 200 cycles with a 100 gram weight on a CF17 Wheel. Solubility: POR-15 is readily soluble in esters. ketones, and aromatic solvents. LABORATORY TEST RESULTS POR-15® 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
A 2 mil thickness of POR-15® 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® 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®
coating was subjected to 700°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®
coating.
ADVANTAGES OVER MOST DUAL-COMPONENT COATINGS Better chemical resistance, better adhesion to metals, greater ease of application, strengthened by exposure to moisture. Reasonable pot life, non-shattering, great flexibility. No catalyst required for curing. CONTAINER AVAILABILITY
