PPG recently announced the launch of an expanded portfolio of coating systems for wastewater facilities. The portfolio includes a combination of the company’s Raven and Aquataflex coating systems for underwater concrete and various coatings for exterior and interior steel.
“PPG is excited to offer a much broader range of coatings solutions for wastewater infrastructure customers thanks to our recent acquisition of VERSAFLEX and its Raven Lining Systems, which are used throughout the water, wastewater and manhole rehabilitation industries,” said Juanjo Ardid, PPG Vice President, Protective and Marine Coatings, U.S. and Canada.
“Wastewater plant operators, engineers and contractors can benefit from having a single resource for proven coatings products backed by the extensive technical support, applications expertise, specification tools and distribution network of PPG.”
The coatings portfolio includes solutions for wastewater management processes, such as collections, primary and secondary treatment, sludge handling and disinfection:
- PPG Raven 405 high-build epoxy coating: Provides heavy-duty protection and broad chemical resistance, especially to hydrogen sulphide (H2S) gases, for challenging concrete immersion applications like wet wells, digesters and manholes;
- PPG AquataFlextri-hybrid series: Combines the chemical resistance of epoxy, the flexibility of polyurethane and fast cure of a polyurea for concrete substrates that are subject to structural movement or that require a quick return to service such as filter basins, clarifiers and tanks;
- PPG Raven755 cementitious resurfacer: Rehabilitates deteriorated concrete as a first coat in a system with PPG Raven 405 or PPG AquataFlex series coatings for manholes, wet wells, filter basins and headworks;
- PPG SIGMASHIELD series: Provides high abrasion and impact resistance for steel-immersion applications due to its ultra-high film build with broad application thicknesses;
- PPG NOVAGUARD 890 novolac epoxy lining: Offers excellent resistance to a wide range of chemicals and solvents, including H2S, for direct-to-metal applications; and
- PPG AMERCOAT interior and PPG AMERLOCK exterior epoxy coatings: Provide versatile, surface-tolerant coatings for atmospheric steel applications in tanks and basins.
According to the press release, the coatings solutions are corrosion resistant and provide long-lasting performance. PPG provides a technical service team that assists with project design and product specification.
