Steel: Self-priming, 66, L69, L69F, N69, N69F, 90-97, H90-97, 90G-1K97, 91-H²O, 94-H²O, L140, L140F, N140, N140F, V140, V140F, 161. Note: The following maximum recoat time applies: over Series 66, L69, N69, L140, N140, V140 or 161, 60 days; over Series L69F, N69F, V69F, L140F, N140F or V140F, 30 days. If the maximum recoat time has been exceeded, the primed surface must be scarified prior to topcoating with Series 22.

Recommended DFT

16 to 40 mils (400 to 1015 microns). Note: For multiple coat applications a minimum 12 mils per coat is required. Note: Dry film thickness that exceeds published recommendations but is in compliance with SSPC PA-2 and ANSI/NSF/CAN Std. 61 certifications is acceptable.


Unthinned: 0.0 lbs/gal solids
Thinned 5%: 0.37 lbs/gal solids

Number of Components

Two: Part A (polyamine) and Part B (epoxy)

Theoretical Coverage

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

Volatile Organic Compounds

Curing Time

Temperature To Touch Dry Through Minimum to Recoat Return to Service Maximum to Recoat
95°F (35°C) 2 1/2 hours 5 1/2 hours 4 hours 5 days 7 days
75°F (24°C) 7 hours 18 hours 16 hours 5 days 7 days
50°F (10°C) 24 hours 27 hours 32 hours 7 days 7 days

Note: These cure times are based on 20.0 mil (500 micron) dry film thickness. Cure 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.
