PPG (NYSE: PPG) has introduced PPG PITT-THERM® 909, a new spray-on insulation (SOI) coating designed for high-temperature applications in the oil, gas, chemical, petrochemical, and infrastructure industries. Unlike traditional waterborne acrylic or epoxy-based coatings, which are limited to temperatures below 350°F (177°C), the silicone-based PPG PITT-THERM 909 withstands continuous and cyclic temperatures up to 500°F, and maintains surface safety up to 310°F, reducing burn risks.
The PPG PITT-THERM 909 coating offers operational efficiency by requiring fewer coats compared to conventional SOI coatings. It can be applied up to 250 mils (6.35 mm) per coat, often needing only one or two coats, which decreases insulation time and costs. Despite the fewer layers, it can achieve a total coating thickness of up to 500 mils with curing times comparable to other products. The coating can be applied to both hot and cold substrates, allowing assets to remain operational during application—an advantage over traditional methods that necessitate shutdowns.
“PPG PITT-THERM 909 reflects our commitment to industry innovation,” said Bill Pernice, PPG Global Segment Director for Oil and Gas, Protective and Marine Coatings. “This product addresses key industry challenges with its high heat resistance and water-repelling properties, enhancing safety and performance in demanding environments.”
Additionally, PPG PITT-THERM 909 mitigates common issues of traditional mechanical insulation systems, such as moisture absorption and corrosion under insulation (CUI). Its water-repellent qualities and proven corrosion resistance make it an effective solution for reducing maintenance costs, operational downtime, and safety incidents.
