Curing Time

Temperature To Touch To Handle Immersion
75°F (24°C) 10 hours 14 hours 3 to 7 days

These times are based on a 50.0 mil (1270 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. Cure time to achieve a minimum Shore D Hardness of 85 or Barcol GYZJ 935 hardness of 79 for immersion service is 3 to 7 days. In order to obtain an accurate reading, the minimum DFT must be 30 mils.

Theoretical Coverage

1,604 mil sq ft/gal (39.4 m²/L at 25 microns). See APPLICATION for coverage rates.



Recommended DFT

Trowelled: 40 mils to 1/4 inch (6.35 mm)
