Generic Type
Modified Polycarbamide
Common Usage
An advanced technology finish coat combining low VOC with exceptional performance. Offers superior color and gloss retention compared to traditional polyurethanes for long-term aesthetics on a wide range of exterior structures. Durable film stands up to abrasion and exterior weathering. Very good brush, roll and spray application characteristics. Direct-to-Metal capability allows for a labor-saving, high-build, single coat application. NOT FOR IMMERSION SERVICE.
Special Qualifications
Series 740 was tested in accordance with, and passed, the California Dept. of Public Health (CDPH) Standard Method v1.2 and meets the requirements of LEED v4.1 Low-Emitting Materials, Collaborative for High Performance Schools-Paints & Coatings, Living Building Challenge Materials Petal 10, and WELL Building Standard v2 X06 VOC Restrictions.
This product is part of a coating system tested in accordance with ISO 12944-6 (2018). Contact your Tnemec representative for coating system test results.

Curing Time
| Temperature | To Touch | To Handle | To Recoat | To Resist Moisture |
|---|---|---|---|---|
| 75°F (24°C) | 2 hours | 6-8 hours | 8 hours | 13 hours |
Curing time varies with surface temperature, air movement, humidity and film thickness. Note: For faster time-to-moisture resistance and low-temperature applications, add No. 44-712 Urethane Accelerator; see separate product data sheet. Note: When topcoating Series 740 with itself, the maximum recoat time is 45 days.
Recommended DFT
Topcoat Service: 2.5 to 6.0 mils (65 to 150 microns) per coat.
Direct-to-Metal Service: 6.0 to 8.0 mils (150 to 205 microns).
Note: Number of coats and thickness requirements will vary with substrate, application method and exposure. Contact your Tnemec representative.
Colors
Refer to Tnemec Color Guide. Note: Certain colors may require multiple coats depending on method of application and finish coat color. When feasible, the preceding coat should be in the same color family (blue, gray, etc.), but noticeably different.
