PPG Sigmashield 880 – High-Build Epoxy Coating for Extreme Corrosion Protection

Single-Coat, Long-Term Protection in the Harshest Marine & Offshore Environments

Two-Component Polyamine Adduct-Cured Epoxy – 5 Gallon Kit

PPG Sigmashield 880 is a two-component, high-build polyamine adduct-cured epoxy engineered for outstanding corrosion resistance under the most extreme conditions. Formulated for rapid immersion service, Sigmashield 880 continues to cure after seawater immersion — making it the go-to coating for offshore splash zones, tidal structures, and subsea applications where conventional coatings simply can't keep up.

Surface tolerant and abrasion resistant, Sigmashield 880 can be applied to wet blast or ultra-high-pressure water-cleaned substrates — damp or dry — and delivers long-term protection in a single coat. From offshore power projects to buried pipelines and marine superstructures, this is the epoxy built for environments that demand the most.

• Rapid immersion capability — continues to cure after seawater immersion, ideal for tidal zones and offshore splash areas
• Single-coat, long-term protection — high-build formula delivers full corrosion protection in one application
• Outstanding seawater resistance — engineered for continuous exposure in marine and offshore environments
• Surface tolerant — suitable for wet blast or UHPWW cleaned substrates, damp or dry
• Abrasion & corrosion resistant — withstands mechanical wear and aggressive chemical exposure
• Cathodic protection compatible — resistant to well-designed CP systems and suitable for exterior buried pipe applications
• Broad chemical resistance — splash and spill resistance to fuels, solvents, alkalis, crude oil, jet fuel, and more
