Single-coat system for tank roof maintenance
PPG Sigmashield™ 880 is an abrasion-resistant, multipurpose epoxy designed for application in the world's most challenging environments. As part of our high-performance tank exterior coating systems, it provides long-lasting protection in a single-coat system.
With a surface-tolerant formulation, it reduces time and costs associated with surface preparation. The coating continues to cure even when exposed to water, providing greater application efficiency for various environmental conditions. It is user-friendly for applicators and offers short dry-to-touch times for rapid return-to-service.
High film build in a single coat
For floating tank roofs, traditional two or three coat systems can be affected by adverse weather conditions. This can disrupt the project schedule and cause delays, especially when standing water on the roof must be removed between coats. Early exposure to rain can also lead to adhesion problems for subsequent coats.
PPG Sigmashield™ 880 can be applied in a single coat to flat plates, reducing application costs and minimizing down time. It can also be applied onto substrates with temperatures of 23°F (-5°C) up to 120°F (48°C), making it an ideal choice for humid, coastal environments.
