Series 94-H2O | Hydro-Zinc

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.
Colors Greenish-gray
Topcoats Interior: Series 20, 20HS, FC20, FC20HS, 22, FC22, L140, L140F, N140, N140F, V140, V140F, 141, 215, 406
Exterior: Series 27WB, 66, 66HS, L69, L69F, N69, N69F, 73, 115, 156, 161, 161HS, 215, 1028, 1029, 1074, 1074U, 1075, 1075U, 1080, 1081. Note: Certain topcoat colors may not provide one-coat hiding depending on method of application. Contact your Tnemec representative. Note: Series 94-H2O must be exterior exposed for three days prior to topcoating with Series 1028 or 1029. Note: Series 94-H2O must be exterior exposed for one day prior to topcoating with Series 27WB.
