Curing Time

Temperature To Recoat Immersion Maximum Recoat
90°F (32°C) 3 hours 24 hours 3 days
75°F (24°C) 4 hours 48 hours 5 days
50°F (10°C) 12 hours 4 days 7 days

Recoat times are typical for coating to be dry-to-touch and ready for the next application. Immersion and certain other services may require longer cure times and/or elevated temperature post cure for optimal performance. ASTM D2583 Barcol Hardness check is also recommended. Coating that has exceeded its maximum recoat time should be checked for styrene or acetone sensitivity or uniformly scarified to assure secondary bonding. Consult Tnemec Technical Services.
