One-component, high-build multi-polymeric composite heat resistant coating to prevent corrosion of insulated and non-insulated carbon steel and stainless steel to temperatures up to 232°C (450°F) and for cryogenic service on stainless steel from -185°C to 232°C (-300°F to 450°F). Also to be used as a primer with PPG HI-TEMP topcoats and with the PPG HI-TEMP 707 HB or PPG HI-TEMP 808 liquid insulation system.

Characteristics
Can be used as a primer with PPG HI-TEMP 500 or 1000 series as a topcoat
Meets CS-1, CS-3 and CS-4 in NACE SP0198-10 for corrosion under insulation
Meets SS-1, SS-2 and SS-3 in NACE SP0198-10 for chloride induced stress corrosion cracking
Can be applied to ambient substrates and to hot substrates having a metal temperature up to 204°C (400°F)
Resistant to thermal shock and thermal cycling in intermittent (wet, dry, wet) service
Forms a superior corrosion resistant system when applied over properly prepared surfaces
