Primers

Self-priming or Series 61, N69F, 161. Note: For surfaces with light to moderate pitting, priming the surface prior to the Series 350 application may help to prevent holidays in the cured film. Note: The following maximum recoat times apply when topcoating with Series 350; 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.

Curing Time

Temperature To Touch To Handle Immersion
75°F (24°C) 3 hours 4 hours 24 to 36 hours

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. Cure time to achieve a minimum Shore D Hardness of 77 or Barcol GYZJ 935 hardness of 55 for immersion service is 24 to 36 hours. In order to obtain an accurate reading, the minimum DFT must be 30 mils.
