Series 73 | Endura-Shield

Generic Type Aliphatic Acrylic Polyurethane
Common Usage A coating highly resistant to abrasion, wet conditions, corrosive fumes, chemical contact and exterior weathering. High build quality combines with project specific primers for two-coat, labor saving systems. NOT FOR IMMERSION SERVICE.
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.
Finish Semi-gloss
Primers Steel: Series 1, 20, 27, 37H, 66, L69, L69F, N69, N69F, 90-97, 91-H2O, 94-H2O, 135, L140, L140F, N140, N140F, 161, 394, 530
Galvanized Steel & Non-Ferrous Metal: Series 27, 66, L69, L69F, N69, N69F, 161
Concrete: 54-660, 66, L69, L69F, N69, N69F, 161
CMU: 54-660
Note: Series 135 or 530 exterior exposed more than two months, or Series N69 or N140 exterior exposed more than three months must first be scarified or reprimed with themselves. Brush blasting with fine abrasive is the preferred method of scarification. Recoat windows for other primers may apply. See those data sheets for additional information.
Topcoats Series 76, 700, 701, 1070, 1071, 1072, 1074, 1074U, 1075U, 1077, 1078, optional when extended weatherability is desired.
Volume Solids 58.0 ± 2.0% (mixed) †
Recommended DFT 2.0 to 5.0 mils (50 to 125 microns) per coat. Note: Number of coats and thickness requirements will vary with substrate, application method and exposure. Contact your Tnemec representative.
Curing Time
Temperature To Touch To Handle To Recoat
75°F (24°C) 1 hour 5-8 hours 12 hours

Curing time varies with surface temperature, air movement, humidity and film thickness. Note: For faster curing and low-temperature applications, add No. 44-710 Urethane Accelerator; see separate product data sheet.
