||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.
||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.

Note: Series 20HS, 66, 66HS, L69, N69, 135, L140, N140, or V140 exposed more than 21 days; Series FC20HS, 27, L69F, N69F, L140F, N140F, V140F, 161 or 161HS exposed more than 14 days; and Series 27WB, 73, or 1075 exposed more than 90 days must first be scarified or reprimed with themselves (or with an epoxy for 73 and 1075) prior to topcoating. Brush blasting with fine abrasive is the preferred method of scarification.

||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.
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.
