Curing Time

Temperature To Touch To Handle Immersion
95°F (35°C) 1/2 hour 2 hours 16 hours
75°F (24°C) 3/4 hour 4 hours 1 day

35°F (2°C) 5 hours 24 hours 12 days

Note: The above cure schedule provides for immersion service, temporary or full storage of recommended chemical exposures below 100°F (38°C). For temperature service >100°F (38°C), consult your Tnemec representative or Tnemec Technical Services. Note: If more than 24 hours have elapsed between coats, the Series 335 coated surface must be mechanically abraded before topcoating.


Self-priming or Series 61, N69F, 161. Note: For surfaces with light to moderate pitting, priming the surface prior to the Series 335 application may help to prevent holidays in the cured film. Note: The following maximum recoat times apply when topcoating with Series 335; Series 61, 14 days; Series N69F and 161, 30 days. If this time limit is exceeded, or if Series N69F or 161 is exterior exposed more than 14 days, the primer must be uniformly scarified prior to topcoating. Note: Series N69F or 161 are for crude oil service only.
