Recommended DFT

16.0 to 40.0 mils (405 to 1015 microns) in a one-coat application. Note: Reference the NSF website at for details on the maximum allowable DFT. Note: Thickness requirements will vary with the substrate, application method, and exposure. Contact your Tnemec representative.


Self-priming or Series 1, 91-H₂O, 94-H₂O, L140, L140F, N140, N140F. Note: The following maximum recoat time applies: over Series L140, N140, 60 days; over Series L140F, N140F, 30 days. If the maximum recoat time has been exceeded, the primed surface must be scarified prior to topcoating with Series FC22.

Curing Time

Temperature To Handle Max to Recoat Immersion
110°F (43°C) 1 hour 7 days 16 hours
75°F (24°C) 6 hours 7 days 24 hours
35°F (2°C) 12 hours 7 days 48 hours

Note: These times are based on a 20.0 mil (500 micron) dry film thickness. Curing time varies with surface temperature, air movement, humidity and film thickness. Ventilation: When used as a tank lining or in enclosed areas, provide adequate ventilation during application and cure. Note: This coating may develop an amine blush or bloom during cure under certain conditions, especially when air and surface temperatures are below 50°F (10°C). During high humidity conditions, it is recommended that the application be done while the temperatures are increasing. While this condition will not adversely affect the performance of the coating, amine blush (or amine bloom), if present, must be removed by washing the surface of the coating film with a blend of 70/30 isopropyl alcohol/water and then abrading the surface before applying additional coats.
