NCSPA Recognizes Dow Polymer Coating

Study shows polymer film provides pipelines with “the best performing” corrosion protection

Trenchcoat Protective Film, from The Dow Chemical Co. has been cited in a study by the National Corrugated Steel Pipe Assn. (NCSPA) as the best performing polymer coating product for protecting corrugated steel pipe (CSP). The polymer, which can be applied to corrugated steel pipes and structural steel plates, is designed as a two-layer adhesive film. It offers corrosion and abrasion protection, and is laminated on the inside and outside of galvanized steel for storm drain and culvert system applications.

Trenchcoat Protective Film provides long-term durability, structural integrity and hydraulic capacity. It was initially developed in 1974 to combine the lightweight and high strength characteristics of galvanized CSP with the chemical resistance and toughness of polymer technology. Trenchcoat resists delamination and bonds physically and chemically to galvanized steel.

The polymer film offering has also been validated in other studies conducted by the NCSPA, fabricators and state departments of transportation.

“With the proven performance of Trenchcoat Protective Films over the last 40 years, as cited in the NCSPA study, we are excited for the opportunity to push this technology to the next level,” Mike Mounts, Performance Plastics development leader at Dow said. “The polymer film offers our customers a high-performance quality material that can withstand extreme environmental conditions, helping to extend the pipe’s lifetime and support the company’s sustainability initiatives."
