Sherwin-Williams Honored for Heat-Flex CUI-Mitigation Coatings

Materials Performance (MP) magazine honored Sherwin-Williams Protective & Marine with a 2025 MP Corrosion Innovation of the Year Award for its Heat-Flex CUI-mitigation coatings during the 2025 Association for Materials Protection and Performance (AMPP) Annual Conference + Expo.

Recognized by a panel of industry experts, the annual award spotlights cutting-edge technologies that significantly advance corrosion control and asset protection on a global scale.

MP chose 10 total winners from 60 submissions, a testament to Heat-Flex CUI-mitigation coatings – including flagship Heat-Flex ACE (Advanced CUI Epoxy), an ultra-high-solids, solvent-free epoxy novolac with a broad dry film thickness range – which were singled out for their ability to slow or prevent damaging corrosion under insulation (CUI), extend service life and reduce operational downtime.

“CUI remains one of the most serious threats to productivity and safety in asset-intensive industries,” says Neil Wilds, global product director of CUI and testing, Sherwin-Williams Protective & Marine. “By delivering robust, long-term corrosion protection that lowers maintenance requirements, our Heat-Flex CUI-mitigation coatings help owners and operators save significant costs while enhancing reliability. We’re proud that Materials Performance has recognized the value and impact of these solutions.”

The Heat-Flex CUI-mitigation portfolio also includes Heat-Flex 750, a high-solids alkylated amide epoxy loaded with micaceous iron oxide for mechanical durability; Heat-Flex 1200 Plus, engineered for harsh environments up to 1200°F (650°C); and Heat-Flex 650, an epoxy phenolic designed for applications up to 401°F (205°C) with enhanced crack resistance and UV stability.

Sherwin-Williams accepted the MP Corrosion Innovation of the Year Award on Monday, April 7, at a special ceremony at the 2025 AMPP Annual Conference + Expo in Nashville, TN.

Sherwin-Williams will maintain a prominent presence at the expo, hosting interactive demonstrations, sharing its latest product offerings and presenting technical sessions exploring solutions for critical corrosion challenges, including:

“In addition to demonstrating our advanced CUI solutions, this year’s AMPP Annual Conference + Expo is the perfect venue to highlight our global core portfolio,” said Grady. “By standardizing formulations worldwide, we help specifiers and asset owners achieve consistent results – no matter where a project is located.”
