Tnemec Company’s innovative Perma-Shield ceramic epoxy lining technology is now available for steel and ductile iron pipe and fittings.  Specifically formulated and tested to withstand severe wastewater environments, Perma-Shield has protected millions of square feet in wastewater collection and treatment plants including manholes, lift stations, headwords, clarifiers, and digesters. 

Series 431 Perma-Shield® PL is a 100% solids, high-build ceramic epoxy lining derived from the successful Perma-Shield line and developed for the unique needs of steel and ductile iron pipe and fittings. A high loading (20% by volume) of high quality, ceramic microspheres adds exceptional abrasion resistance to an already durable epoxy film, and its low permeation rate provides a highly impenetrable barrier to H2S and other sewer gases. Series 431 applies quickly in one or two coats allowing fast and efficient through-put of pipe and fittings.
