Recommended Uses
For use on properly prepared steel or masonry surfaces including immersion (non-potable water) service. Also for concrete floors, interior primed drywall, plaster, and wood surfaces. Ideal for structural steel, piping, storage tanks, machinery, and equipment in petroleum refineries, pulp and paper mills, chemical and fertilizer plants, and sewage treatment plants. Can also be used in the hard service areas of food processing plants, dairies, schools, restaurants, and general industrial buildings and structures. Suitable for use on structural surfaces or surfaces where there is a possibility of incidental food contact in commercial food preparation establishments, food processing plants and federally inspected meat and poultry plants. USDA no longer requires or furnishes product certification letters.
- Theoretical Coverage at 1.0 Mil (25 microns) Dry: 1091 sq.ft./gal. (28.0m2 /L)
- Recommended Film Thickness: 4.0 – 8.0 mils (100 – 200 microns) dry – 5.9-11.7 mils (147-293 microns) wet. (Make allowances for loss due to overspray & irregular surfaces.)
Minimum Dry Time (ASTM D 1640): At 5 mils (125 microns) DFT Substrate Temperature 20°F (-7°C) 40°F (4°C) 60°F (16°C) 80°F (27°C) Minimum Recoat 28 hours 11 hours 6 hours 3 hours Dry Hard 46 hours 18 hours 9 hours 5 hours Maximum Recoat 30 days 30 days 30 days 30 days Limitations Of Use
Exterior exposure will cause a color change, early dulling, and loss of gloss, but this does not affect protective properties. Epoxy coatings may yellow during application and cure if exposed to the combustion byproducts of improperly vented fossil fuel burning heaters.
