The online catalog at www.tnemec.com should be referenced for the most current technical data and instructions or you may contact your Tnemec representative for current technical data and instructions. Endura-Shield® SERIES 73 PRODUCT PROFILE GENERIC DESCRIPTION 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 SPECIAL QUALIFICATIONS Series 73 meets the requirements of SSPC-36 Paint Standard. PERFORMANCE CRITERIA Extensive test data available. Contact your Tnemec representative for specific test results. COATING SYSTEM PRIMERS Steel: Series 20, 37H, 66, N69, 90-97, 91-H20, 104, 135, N140, 161 Galvanized Steel and Non-Ferrous Metal: Series 66, N69 Concrete: 54-660, 66, N69, 104 CMU: 54-660 Note: Series 104 or 135 exterior exposed more than two months, or Series N69 or N140 exterior exposed more than three months must first be scarified or reprimed with them- selves. Brush blasting with fine abrasive is the preferred method of scarification. TOPCOAT Series 76, optional when extended weatherability is desired. SURFACE PREPARATION ALL SURFACES Must be clean, dry and free of oil, grease and other contaminants. TECHNICAL DATA 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.

(2) Can be sprayed, brushed or rolled at 2.0 to 3.0 mils (50 to 75 microns) DFT per coat for use in systems requiring a conventional build topcoat. Allow for overspray and surface irregularities. Film thickness is rounded to the nearest 0.5 mil or 5 microns. Application of coating below minimum or above maximum recommended dry film thicknesses may adversely affect coating performance. MIXING Stir contents of the container marked Part A, making sure no pigment remains on the bottom. Add the contents of the can marked Part B to Part A while under agitation. Continue agitation until the two components are thoroughly mixed. When used with 44-710 Urethane Accelerator, first blend 44-710 into Part A under agitation; continue as above. Do not use mixed material beyond pot life limits.Caution: Part B is moisture-sensitive and will react with atmospheric moisture. Keep unused material tightly closed at all times. POT LIFE 8 hours at 40°F (4°C) 4 hours at 77°F (25°C) 2 hours at 100°F (38°C) THINNING For air spray, thin up to 10% or ¾ pint (380 mL) per gallon by volume with No. 42 Thinner if temperatures are below 80°F (27°C), use No. 48 Thinner for temperatures above 80°F (27°C). Thin up to 5% or ¼ pint (190 mL) per gallon for airless spray. For brush or roller, thin 5% to 10% or ¼ to ¾ pint (190 to 380 mL) per gallon with No. 39 Thinner. Thinning is required for proper brush or roller application. Caution: Do not add thinner if more than thirty (30) minutes have elapsed after mixing. SURFACE TEMPERATURE Minimum 35°F (2°C) Maximum 120°F (49°C) The surface should be dry and at least 5°F (3°C) above the dew point. Cure time necessary to resist direct contact with moisture at surface temperature: 40°F (4°C): 24 to 40 hours 50°F (10°C): 18 to 26 hours 60°F (16°C): 12 to 16 hours 70°F (21°C): 4 to 8 hours 90°F (32°C): 2 to 4 hours 100°F (38°C): 2 to 3 hours If the coating is exposed to moisture before the preceding cure parameters are met, dull, flat or spotty-appearing areas may develop. Actual times will vary with air movement, film thickness and humidity.

Roller: Use 1/4” (6.4 mm) synthetic nap cover. Do not use medium or long nap roller covers. Note: Two coats are required to obtain dry film thickness above 3.0 mils (75 microns). Brush: Recommended for small areas only. Use high quality natural or synthetic bristle brushes. Note: Two or more coats may be required to obtain recommended film thicknesses. CLEANUP Flush and clean all equipment immediately after use with the recommended thinner or MEK. *Values may vary with color.
