PPG launch new product for extreme temperature

0

PPG’s protective and marine coatings business has launched PPG HI-TEMP 900, its latest solution for application in extreme operating conditions.

Resistant to temperatures ranging from -321°F to 900°F (-196°C to 482°C), PPG HI-TEMP 900 is suitable for application in petrochemical, refining, power, offshore, pulp and paper and other industrial facilities.

Ideal for new building application, PPG HI-TEMP 900 offers multi-purpose, high-temperature corrosion protection with very high speed of application and handling.

Applicable as a primer, the coating offers a simple two-component product with complete crosslink curing at ambient temperatures and can be top coated with custom colours. The ability to apply the coating in one coat provides excellent speed of application and handling in the shop.

Consistent with the PPG HI-TEMP range, PPG HI-TEMP 900 is designed to provide superior surface corrosion resistance and prevent corrosion under insulation. Its Corrosion Under Insulation (CUI) capability has been tested and verified using third-party testing in a multi-phase CUI chamber test. In addition, the coating offers excellent UV stability to prevent corrosion of non-insulated surfaces subject to atmospheric exposure.

“Corrosion Under Insulation is one of the industry’s major concerns because it can lead to high costs for refineries and petrochemical facilities in cases of facility shutdowns, environmental issues or personal injury,” says Ronald Li, Global HI-TEMP Manager at PPG. “PPG HI-TEMP 900 has been designed to resist the severe ‘real world’ conditions of a continually-changing harsh environment and was developed to withstand the repeated cycle of thermal shock, a significant cause of CUI.”

Thermal shock can cause cracking, fracturing and delamination, allowing water to come into contact with the base layer of steel and potentially leading to CUI. PPG HI-TEMP 900 is able to withstand severe cyclic hot-cold conditions without affecting the coating performance.

Numerous international refineries and petrochemical facilities have used the PPG HI-TEMP coatings for over a decade and a half, with millions of square meters protected from CUI and able to provide a consistent level of high-temperature service.
