Series 1074 (or 1074U) | Endura-Shield II

Generic Type Aliphatic Acrylic Polyurethane
Common Usage A coating highly resistant to abrasion, wet conditions, corrosive fumes and exterior weathering. High build quality combines with project specific primers for two-coat, labor saving systems. Fast curing options are available; see Curing Time below. For additional protection from ultra-violet light, Series 1074U is available. 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, but noticeably different.
Finish Gloss
Primers Steel: Series 1, 20, FC20, 27, 66, L69, L69F, N69, N69F, 90-97, 91-H2O, 94-H2O, 104, 135, L140, L140F, N140, N140F, 161, 394, 530
Galvanized Steel and Non-Ferrous Metal: Series 27, 66, L69, L69F, N69, N69F, 135, 161
Concrete: Series 66, L69, L69F, N69, N69F, 84, 104, 161
CMU: 54-660, 130. Intermediate coat required.
Note: Before topcoating with Series 1074, Series 530 exterior exposed for more than 24 hours must first be scarified or receive an intermediate coat of Tnemec polyamide epoxy. Recoat windows for other primers may apply. See those data sheets for additional information.
Volume Solids 66 ± 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 Handle To Recoat Resist Moisture
95°F (35°C) 4 hours 5 hours 3 hours
75°F (24°C) 6 hours 8 hours 5 hours
55°F (13°C) 12 hours 16 hours 9 hours
35°F (2°C) 36 hours 48 hours 20 hours

Curing time varies with surface temperature, air movement, humidity and film thickness. If coating is exposed to moisture before the applicable cure parameters are met, dull, flat or spotty appearing areas may develop. Note: For faster curing and low-temperature applications, add No. 44-710 Urethane Accelerator; see separate product data sheet. Contact Tnemec Technical Services for force curing times and temperatures.
