The Proven Ceramic Epoxy Lining: Protecto 401™

Nothing protects tough sewer pipe applications more effectively than ductile iron pipe and fittings lined with Induron’s Protecto 401™ Ceramic Epoxy. It’s been successfully used in hundreds of sanitary sewer applications and proven both in laboratory testing and decades of actual sewer service.

The history of Protecto 401™

In 1979, Induron Coatings initiated a two-year research and development process that led to the industry-leading product known as Protecto 401 today. The first Protecto 401-lined ductile iron sewer pipe was placed into service in 1981. Since then, thousands of miles of ductile iron sewer pipe have been lined with Protecto 401. 

About Protecto 401™

Specifically designed to protect ductile iron sanitary sewer pipe, Protecto 401 Ceramic Epoxy Lining provides the reliability of cement mortar lining with the unequaled corrosion protection of novolac epoxy. Its unique qualities have resulted in performance unmatched by any other lining. 

Protecto 401™ is: 

  • A superior internal lining for corrosion and abrasion resistance for sewer applications, resulting in an extended life of the system.
  • Non-hazardous and safe for our environment, ensuring confidence in using a quality product that is safe.
  • Non-toxic coating (no volatile organic compounds).
  • Non-flammable (no solvents in its compound).
  • An exceptional alternative to other linings available in the market.
  • Recoatable (Protecto 401 joint compound shall be used for touch-up or repair in accordance with manufacturer’s recommendations).

Protecto 401 is applied to the interior of ductile pipe and fittings, utilizing specialized application equipment and stringent specifications. The lining is designed to be applied at a nominal 40-mil thickness. A nondestructive pinhole detection test, and a thickness test, are performed to ensure a sound, chemically-resistant protective lining for ductile iron pipe and fittings. Over the years, Protecto 401 has been exhaustively tested and evaluated by both Induron’s own research and development professionals as well as independent laboratories.
