Series 431 | Perma-Shield PL

Generic Type Modified Polyamine Ceramic Epoxy
Common Usage A 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 steel, ductile iron pipe and fittings for severe wastewater. A coal-tar free, resin-rich formulation with low pigment volume concentration (PVC) for maximum performance.
Colors 5024 Sewer Pipe Green. Note: Epoxies chalk with extended exposure to sunlight.
Finish Gloss
Primers Self-priming, Series N69 or Series N140. Note: Series 431 must be applied to Series N69 or N140 within 7 days. Scarify the surface with fine abrasive before topcoating if exceeding this maximum recoat window.
Volume Solids 100% (mixed)
Recommended DFT Carbon Steel: 30.0 to 50.0 mils (762 to 1270 microns) in one or more coats.
Ductile Iron: 40 mils (1015 microns) (nominal) in one or more coats.
Note: Number of coats and thickness requirements will vary with substrate, application method and exposure. Contact your Tnemec representative.
Curing Time
