Superior corrosion protection in extreme temperatures

PPG HI-TEMP 900 is a multipurpose heat-resistant coating that prevents corrosion of insulated and non insulated carbon and stainless steel over an extreme temperature range from 300°F to 900°F (–185°C to 482°C).

Resistant to boiling water

Designed to resist severe 'real world' conditions of a continually changing harsh environment, PPG HI-TEMP 900 is able to withstand the repeated cycle of thermal shock, immersion in boiling water, and quench.

Resistant to thermal shock

A leading cause of CUI, thermal shock causes cracking, fracturing, delamination and allows water to come into contact with insulated steel. PPG HI-TEMP 900 is able to withstand severe cyclic conditions and continues to provide long-lasting protection.

Prevents CUI – lowers maintenance costs

These properties make PPG HI-TEMP 900 an effective solution for combatting Corrosion Under Insulation (CUI) - and avoiding the high costs of rectifying this major problem. Thanks to its one-coat application and ability to cure at ambient temperatures, PPG HI-TEMP 900 is also simple to use.

Established worldwide track record

A number of first class international refineries and petrochemical facilities have used and trusted our PPG HI-TEMP heat resistant coatings for many years. Thanks to the exceptional and long-lasting performance of these products, millions of square meters are now protected from CUI and high-temperature service.
