Curing Time
| Temperature | To Touch | To Handle | To Recoat |
|---|---|---|---|
| 75°F (24°C) | 1 hour | 5-8 hours | 12 hours |
Curing time varies with surface temperature, air movement, humidity and film thickness. Note: For faster curing and low-temperature applications, add No. 44-710 Urethane Accelerator.
Primers
Steel: Series 1, 20, 27, 27WB, 37H, 66, L69, L69F, N69, N69F, V69, V69F, 90-97, 91-H₂O, 94-H₂O, 135, L140, L140F, N140, N140F, V140, V140F, 161, 394, V530
Note: Series V530 exterior exposed more than 24 hours, Series 135 exterior exposed more than two months, or Series N69 or N140 exterior exposed more than three months must first be scarified or reprimed with themselves. Brush blasting with fine abrasive is the preferred method of scarification. Recoat windows for other primers may apply. See those data sheets for additional information.
