Curing Time

Temperature To Touch To Handle To Recoat Immersion
95°F (35°C) 1 hour 3 hours 6-7 hours 7 days
75°F (24°C) 2 hours 8 hours 12-16 hours 7 days
55°F (13°C) 4 hours 22-24 hours 30-34 hours 12-14 days

Curing time varies with surface temperature, air movement, humidity and film thickness. Note: For faster curing and low temperature applications, add No. 44-705 Epoxy Accelerator, see separate product data sheet for cure information.
Ventilation: When used as a tank lining or in enclosed areas, provide adequate ventilation during application and cure.
