PPG announced that its PPG PSX™ polysiloxane coatings have been tested successfully by an independent, third-party laboratory to the requirements for C4H (or high C4) certification under the ISO 12944-6:2018 international standard for corrosion protection of steel structures by paint systems.
PPG’s patented PSXcoatings use a polysiloxane resin technology from Dow to provide long-term corrosion, weathering and chemical resistance in exposed steel applications, including stadiums, arenas, water towers and hospitals foyers, with fewer coats than traditional systems.
“C4H certification is a significant achievement for the PPG PSX coating portfolio,” said Scott Doering, director of sales and technical service, protective and marine coatings, U.S. at PPG.
“It confirms the long-term protection these products can offer for steel assets in even very challenging conditions with fewer coats. We’re proud to offer customers this unique combination of high performance with lower environmental impacts,” said Doering.
Because of these performance capabilities, specifying a PPG PSX coating can result in material cost savings, less energy-intensive production and application, and fewer recoats over time.
