PPG’s new PPG Pitt-Therm 909 spray-on insulation (SOI) coating protects assets, promotes safety and increases operational efficiency in critical infrastructure industries such as oil and gas, chemical and petrochemical, the company announced Aug. 21.

Designed for high heat environments, the silicone-based coating offers greater temperature resistance than conventional waterborne acrylic or epoxy-based SOI coatings. Application testing of PPG Pitt-Therm 909 also requires fewer coats to be just as effective as traditional SOI coatings.

PPG Pitt-Therm 909 coating addresses traditional mechanical insulation system challenges, specifically susceptibility to moisture absorption and corrosion under insulation. The coating’s water-repellent capabilities demonstrate corrosion resistance to reduce maintenance costs, operational shutdowns and safety incidents.

Application to both hot and cold substrates is also viable, allowing assets to remain in service during application, an advantage over traditional methods requiring operational shutdowns.
