Curing Time

Temperature To Handle To Recoat (Max) Immersion
75°F (24°C) 8 hours 7 days 7 days

These times are based on a 20.0 mil (500 micron) dry film thickness. Higher film thicknesses, insufficient ventilation or cooler temperatures will require longer cure times. This coating commonly develops an amine-blush during cure. While this condition will not adversely affect performance of the coating, this blush must be removed by aggressive sweep blasting before applying additional coats. During high humidity conditions, it is recommended that the application be done while the temperatures are increasing.

Recommended DFT

20.0 to 40.0 mils (508 to 1,016 microns) one coat with multiple passes.
