Generic Type Modified Polyamine Epoxy
Common Usage A versatile, thick film, 100% solids, abrasion-resistant lining specifically designed for wastewater immersion and fume environments. Provides low permeation to H2S gas, protects against MIC and provides chemical resistance to severe wastewater environments.
Colors 5020 Gray, 5023 Beige. Note: Epoxies chalk with extended exposure to sunlight.
Finish Gloss
Surfacer/Filler/Patcher Series 215, 217, 218.
Primers Concrete: Self-priming or Series 201.
Steel: Self-priming or Series N69. Note: Series 435 must be applied to Series N69 within 7 days. Scarify the surface with fine abrasive before topcoating if exceeding this maximum recoat window.
Intermediate Series 434 or 436 (optional)
Volume Solids 100% (mixed)
Recommended DFT Steel: 15.0 to 40.0 mils (380 to 1015 microns) in one or two coats.
Concrete: 30.0 to 40.0 mils (760 to 1015 microns) in one or two coats.
Hi-Build Option: 40.0 to 80.0 mils (1015 to 2030 microns) in one or two coats.
Glaze Coat Option (over Series 434 or 436): 15.0 to 20.0 mils (380 to 510 microns).
Note: Number of coats and thickness requirements will vary with substrate, application method and exposure. Contact your Tnemec representative.
Curing Time
Temperature To Touch Dry Through To Place in Service Max. Recoat
75°F (24°C) 3 hours 14 hours 2 days 7 days
55°F (13°C) 7 hours 30 hours 3 days 7 days
Note: If more than 7 days have elapsed between coats, the Series 435 coated surface must be mechanically abraded before topcoating. Curing time will vary with surface temperature, air movement, humidity and film thickness. Note: Use “To Touch” cure information for minimum recoat times if succeeding coats are spray-applied and “Dry Through” if succeeding topcoats are applied by roller or brush.
