|Generic Type||Aromatic Urethane, Zinc-Rich|
|Common Usage||A single-component, moisture-cured, zinc-rich primer for steel structures, including the interior and exterior of steel potable water tanks. Provides outstanding long-term corrosion resistance when used as a primer in conjunction with other Tnemec coatings. It cures quickly and offers rapid recoat at surface temperatures down to 35°F. Note: When used in conjunction with cathodic protection, anodes or impressed current systems should not provide current demand more negative than –1.05 volts relative to a copper–copper sulfate reference electrode half-cell.|
|Topcoats||Interior: Series 20, FC20, 22, FC22, L140, L140F, N140, N140F, V140, V140F
Exterior: Series 66, L69, L69F, N69, N69F, V69, V69F, 73, 115, 156, 161, 1028, 1029, 1074, 1074U, 1075, 1075U, 1080, 1081.
