PPG PSX Coatings Receive C4H Certification for Corrosion Resistance

Rhea-AI Summary

PPG has announced that its patented PPG PSX™ polysiloxane coatings have achieved C4H certification under the ISO 12944-6:2018 standard for corrosion protection. This certification signifies long-term protection against corrosion in harsh environments, such as industrial and coastal areas, with an estimated durability of 15 to 25 years. The PSX technology requires fewer coats compared to traditional systems, leading to material cost savings and reduced environmental impact. The coatings are also ultra-high solids and isocyanate-free, meeting stringent emissions regulations.

Positive

• Achieved C4H certification under ISO 12944-6:2018 for long-term corrosion protection.
• Estimated durability range of 15 to 25 years in harsh environments.
• Requires fewer coats than traditional systems, resulting in potential material cost savings.
• Ultra-high solids and isocyanate-free formulations comply with strict environmental regulations.

Negative

• None.

Performance testing demonstrates patented polysiloxane technology provides long-term steel protection in challenging environments with single coat

PITTSBURGH--(BUSINESS WIRE)-- PPG (NYSE: PPG) today 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 PSX 700 and PPG PSX 805 coatings that are applied directly onto metal in a single coat demonstrated corrosion resistance that meets high C4 requirements, which estimate a durability range of 15 to 25 years.

PPG’s patented PSX coatings 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. Other coating technology can require multiple coats to achieve the same level of protection as a single PPG PSX topcoat or two-coat PSX coating system incorporating a zinc primer. 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.

“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. “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.”

In addition to requiring fewer coats to achieve the same level of protection as alternative systems, PPG PSX coatings are ultra-high solids and isocyanate-free to meet the most stringent environmental emissions regulations. They also offer excellent color and gloss retention by resisting the fading, chalking and general deterioration over time that are a common limitation of more traditional finishes, such as epoxies and acrylic urethanes.
