PPG Introduces Hi-Temp 707 HB Spray-on Insulation Coating

PPG Industries' protective and marine coatings (PMC) business has unveiled worldwide PPG HI-TEMP 707 HB spray-on insulation coating, which delivers high levels of personal protection and energy efficiency while preventing corrosion under insulation (CUI).

Developed to operate under extreme conditions where pipes and other assets are exposed to process temperatures between -57 and 177 C (71 and 351 F), PPG Hi-Temp 707 HB spray-on insulation coating provides excellent personal protection from getting burned for workers and complies with the ASTM C 1055 standard. The standard requires that the surface temperature of the part of an asset that is accessible to workers be in the “safe zone” (approximately 58 to 60 C, or 137 to 140 F) so the surface can be touched for as long as 5 seconds without resulting in a skin burn.

Designed to offer a simple, spray-on and seamless alternative to expensive mechanical insulation methods, PPG Hi-Temp 707 HB coating can be applied directly onto surfaces as hot as 150 C (302 F). With the ability to be spray-applied at 1,250 micrometers (50 mils) per coat, application is easy and the speed of application reduces the cost of insulating assets by as much as 33 percent. Furthermore, the coating has been proven to deliver energy savings of 9 percent compared to competitive spray-on insulation products.

“Petrochemical, nuclear and process plants are some of the most extreme industrial applications for a coatings system, requiring a close understanding of the environment the product must address," said Mike MeLampy, PPG global business development director. "For people working within these facilities safety is the No. 1 priority, and PPG Hi-Temp 707 HB spray-on insulation coating has been proven to be a safe solution for those working directly with it, both within laboratory and field tests. It provides outstanding anticorrosion properties with insulation and aesthetics, making this a unique solution for long-term asset protection.”

When used in combination with a primer and topcoat, PPG Hi-Temp 707 HB spray-on insulation coating completely seals the asset, ensuring there are no gaps or crevices for moisture or contaminants to penetrate, thus reducing the costly risk of CUI. However, if CUI does occur, visual detection is quick and easy – a major advantage for maintenance managers as, when mechanical insulation materials are used, CUI is not immediately visible and often remains undetected until the damage is significant.
