Fast-Set Urethane 530 is a low viscosity, fast curing, two-component polyurethane elastomer.
USAGE
Intended for use as a fast curing high build protective coating over polyurethane foam insulation, modified bitumen, built up roofs, and other suitable substrates.
CHEMICAL RESISTANCE:
Good resistance to salts, hydrocarbon solvents, acids and alkalis. Fair resistance to oxygenated and chlorinated solvents. Good hydrolytic stability.
WEATHERABILITY:
Excellent durability and chalk resistance.
APPLICATION:
Stirring may be required to ensure uniformity of the material, particularly if products have been stored at temperatures outside of the recommended range. (See storage stability information below.)
Apply with plural component airless equipment. Material must be maintained between 120°F (49°C) and 140°F (60°C) during application. For best results maintain pressures at or above 2,000 psi. May apply up to 60 mils (1.52 mm) in

| Toxicity | Part B contains polymeric diisocyanate, which is toxic if heated in a confined area or inhaled as particulate matter. An air supply respirator is required for spray applications and containers of Part B should not be heated above 120°F (49°C). However, heating of either component to 140°F (60°C) is acceptable when using plural component spray equipment. | ||||||
| Adhesion: | Adheres well to polyurethane foam, modified bitumen, and other roof substrates. It is recommended that FAST SET URETHANE 530 be applied in a single pass. | ||||||

||||||
| Thinner: | Do not thin. | ||||||
| Cure: | Applied coating will cure in 24 hours with 70ºF (21ºC) and 40% relative humidity. Lower temperatures and humidity will require longer times to cure. | ||||||
| Clean Up: | Spray equipment may be cleaned with T-5112 thinner. |
