Series 1

Omnithane

Generic Type

Modified Aromatic Polyurethane Primer

Common Usage

A single component, moisture-cured resin, containing a proprietary blend of micaceous iron oxide and zinc to function as a primer which is field and shop friendly. May be used in OEM manufacturing, potable water and wastewater immersion with the proper topcoats. May also be used for marginally prepared rusty steel and tightly adhering old coatings for non-immersion maintenance situations.

Special Qualifications

NSF: Certified in accordance with ANSI/NSF Std. 61 for potable water applications (for tanks of 1,000 gallons capacity or greater, pipes 36 inches in diameter or greater or valves 4 inches in diameter or greater) when topcoated (with or without 44-710 Urethane Accelerator) with Std. 61 certified Tnemec coatings.
AISC: Meets AISC requirements in accordance with RCSC Appendix A for Class B surface with a mean slip coefficient no less than 0.50 and tension creep not in excess of .005 inches (.13 mm). Contact Tnemec Technical Service for more information. Note: Using other products as primers or topcoats voids AISC requirements. Contact your Tnemec representative for specific recommendations.

Curing Time

Without 44-710

| Temperature †|| To Touch || To Handle || To Topcoat |
| 75°F (24°C) || 1/4 hour || 1 1/2 hours || 16 hours |
| 65°F (18°C) || 1/4 hour || 2 3/4 hours || 16 hours |
| 55°F (13°C) || 1/4 hour || 5 hours || 20 hours |
---† 50% Relative Humidity. Note: Refer to product listings on www.nsf.org for specific potable water return to service information. Curing time will vary with surface temperature, humidity and film thickness.
Note: When recoating Series 1 with itself, the minimum recoat time is 2 hours at 70°F (21°C).
Ventilation: When used in enclosed areas, provide adequate ventilation during application and cure.

With 44-710: The use of 44-710 can greatly reduce dry to handle cure times. Note: Series 44-710 Accelerator must be used when the surface temperature falls below 50°F (10°C).
