PPG PSX Coatings Receive C4H Certification for Corrosion Resistance
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. Under this standard, an exposure environment classified as C4 is described as highly corrosive. Such environments include industrial and coastal areas with moderate salinity and interior exposure environments like chemical plants, natatoriums, and coastal shipyards and boatyards.
PPG’s patented PSX 700 and PPG PSX 805 coatings that are applied directly onto metal in a single coat which can achieve a durability range of 15 to 25 years. The PSX coatings use a polysiloxane resin technology from Dow to provide long-term corrosion, weathering, and chemical resistance in many exposed steel applications with fewer coats than traditional systems. PPG PSX coating can result in material cost savings, less energy-intensive production and application, and fewer recoats over time. PPG PSX coatings are ultra-high solids and isocyanate-free to meet the most stringent environmental emissions regulations.
