The new PPG PITT-THERM 909 spray-on insulation coating offers high temperature resistance, protecting both operators and critical assets.
The international paints and coatings manufacturer PPG has recently announced the launch of the new PPG PITT-THERM® 909 spray-on insulation (SOI) coating, a silicone-based solution that has been specifically developed to improve the safety, protection and efficiency oil and gas, chemical, petrochemical and other critical infrastructure assets operating in high-heat environments.
Usually, conventional water-based acrylic or epoxy spray-on insulation coatings cannot be used on equipment operating above 350 F. However, the new PPG Pitt-Therm 909 coating offers much greater temperature resistance: thermal testing shows that it endures continuous and cyclic temperatures as high as 500 F. Furthermore, by reducing heat transfer, the external surfaces remain safe to touch at up to 310 F, significantly reducing the risk of burns.
Moreover, other application testing has demonstrated that it required fewer coats: as a matter of fact, PPG Pitt-Therm 909 can be applied in thicknesses of up to 250 mils per coat and – depending on the specific application requirements – only one or two coats are needed. Yet, despite the reduced number of layers, it can achieve a higher total coating thickness of up to 500 mils and cure times are comparable to competing products.
Finally, the SOI coating PPG Pitt-Therm 909 addresses also the critical challenges associated to the traditional mechanical insulation systems, such as susceptibility to moisture absorption and corrosion under insulation (CUI). Since it is water-repellent, the new product has demonstrated exceptional corrosion resistance in rigorous testing.
“PPG Pitt-Therm 909 coating represents our team’s ongoing commitment to advancing industry standards through innovation. This solution tackles the long-standing challenges of the industry by delivering high heat resistance and water-repelling properties, elevating safety and performance in demanding environments,” has stated Bill Pernice, the global director of the oil and gas segment for the Protective and Marine Coatings division of PPG.
The new coating from PPG can be applied to both hot and cold substrates, allowing assets to remain in service during application. Available in the United States of America and Canada, PPG Pitt-Therm 909 meets requirements for the American Society for Testing and Materials (ASTM) E84 Class A fire rating.
