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.

Colors

Refer to Tnemec Color Guide. Note: Epoxies chalk with extended exposure to sunlight and may yellow on aging. Lack of ventilation, incomplete mixing, miscatalyzation or the use of heaters that emit carbon dioxide and carbon monoxide during application and initial stages of curing may accelerate any potential yellowing. Note: Special color bases are recommended for immersion service. Contact your Tnemec representative for more information.
