The salt spray resistance of all properly applied and primed Duravin thermoplastic powder coatings is excellent. A zinc or iron phosphate substrate, primed with the recommended Duravin primer and coated with the above product, will provide a durable finish showing no effect in 5,000 hours of salt spray exposure and less than 1/8" undercutting will be observed on a scored panel exposed for 2,000 hours.
