Dura-Steel 316™ OC is different in that it is a one coat product that both primes and finishes in a one coat application and yet offers the corrosion protection of most two-coat systems. Dura-Steel 316 OC passes ASTM B-117 salt spray testing for 1000 hours. While Dura-Steel 316 OC can be used directly to the metal in a one coat application, it also works extremely well as a primer for all of our stainless and non-stainless topcoats.
Dura Steel OC 316 water-based two-party epoxy metal primer is a heavy duty metal epoxy primer/finish for use on the metal where maximum long-term protection is desired. It’s a zinc free, chip resistant formula, reinforced with 316 stainless steel flake. The VOC is under 110 g/l to comply with stricter VOC standards and is HAPS free.
How to Apply Metal Epoxy Metallic Stainless Steel Primer:
Only Apply Dura-Steel OC 316™ when air and surface temperatures are between 50oF and 100oF and surface temperature is at least 5oF above the dew point.
Preparing the Metal Surface for Epoxy Primer Coating:
Remove all dirt, grease, oil, salt, and chemical contaminants by washing the surface with BC-4000 cleaner or other suitable cleaners. Thoroughly cured old coatings or new smooth metal may require scuff sanding for maximum adhesion. Aluminum surfaces should be washed with BC7000 and rinsed with clean water prior to applying stainless steel epoxy metal primer – finisher.
Mixing: 3 to 1 mix water-based epoxy gray stainless steel primer for metal
For Moderate Exposure Metal: Abrasive blast to SSPC-SP-6 commercial blast before priming.
For Severe Exposure Metal: An abrasive blast to SSPC-SP-10 near white blast before priming.
Required Curing Agent: 16-500B; mixing ratio (3) parts “A” + (1) part “B” by volume
