Curing time varies with surface temperature, air movement, humidity and film thickness. For immersion service cure a minimum of 24 hours at 75°F (24°C). The following minimum recoat times apply when topcoating with Series 297, 1080 or 1081: 95°F (35°C) 12 hours, 75°F (24°C) and 55°F (13°C) 24 hours, 45°F (7°C) 4 days, 35°F (2°C) 7 days. Note: For faster cure in temperatures down to 35°F (2°C), add No. 44-700 Epoxy Accelerator, see separate product data sheet for cure information. Note: The use of Series 44-700 Accelerator is not recommended when temperatures exceed 75°F (24°C).
