Archco 476 High-Performance Phenolic-Novolac Epoxy Linings Deliver Industry-Leading Chemical and Temperature Resistance

Denso, Inc., a global leader in corrosion prevention, is proud to highlight its Archco 476 Series™, a comprehensive range of high-performance, two-part phenolic-novolac epoxy linings formulated to safeguard tanks and piping systems in the most demanding environments. The Archco 476 Series sets a benchmark for corrosion protection and long-term asset performance, harnessing cutting-edge epoxy technology and robust development to ensure advanced resistance to chemical, high pressures and high service temperatures.

Designed specifically for applications where internal linings must withstand extreme temperature conditions, the Archco 476, 476F, 476LT, and 476P Epoxy products each offer a distinct set of technical advantages tailored to industry needs. Each formula in the series provides exceptional corrosion protection for steel tanks, vessels, and pipes, ensuring reliable defense against crude oil, seawater, wastewater, fuels, solvents, and lubricants. All systems within the range exhibit excellent adhesion and outstanding chemical resistance, delivering high temperature immersion protection up to 275°F (135°C) where specified and maintaining performance over a broad spectrum of operating pressures.

The standard Archco 476 Epoxy features an 85% solids composition optimized for single-leg airless spray application, providing robust service life and fast cure cycles that minimize downtime. For lining applications requiring enhanced durability and reinforcement, Archco 476F Epoxy integrates a proprietary blend of flake and fiber, meeting API RP 652 guidelines for thick-film linings and offering excellent abrasion and impact resistance. This reinforced formula ensures resilience in harsh, high-abrasion service up to 250°F (121°C), making it the ideal choice for environments exposed to mechanical stress or volatile materials.

For installations where ambient temperatures pose a challenge, Archco 476LT Epoxy allows plural-component spray application at temperatures as low as 20°F (-7°C), supporting projects that require expedited return to service and cold-weather functionality. Its 100% solids content and fast cure ensure efficient project turnaround without sacrificing protective qualities, even in challenging field conditions. The Archco 476P Epoxy offers a specialized plural-component, 100% solids solution engineered for high-build applications up to 40 mils DFT. Zero VOC emissions make this solution compliant with stringent regulations, while its high temperature and chemical resistance offer peace of mind for specifiers working in environmentally controlled sectors.

The Archco 476 Series™ delivers cathodic disbondment resistance, helping prevent underfilm corrosion and amplifying long-term asset reliability. Each system is designed for straightforward field application and dependable adhesion, withstanding aggressive chemical and temperature fluctuations. With this advanced solution, Denso reinforces its commitment to delivering innovative, high-performance solutions for industrial infrastructure protection.
