PPG HI-TEMP 1027 HD is a two pack ambient cured multi-polymeric heat resistant coating system.

Best Uses

PPG Hi-Temp 1027 HD is 2-pack coating that can be applied and then shipped next day will little/no damage from straps/chains in transit. Offers improved coating for modular construction.

After transit, use PPG Hi-Temp 1027 on site for welds and touch up etc.

• Designed to prevent corrosion under insulation (CUI) of carbon steel and stainless steel
• Enhanced wear resistant coating for ease of transport
• New-build, shop, and field application
• Cyclic temperature resistance from -196°C (-320°F) to 540°C (1000°F)
• Resistant to thermal shock / cycling and intermittent immersion and boiling water
• Resistant to dry operating windows up to 650°C (1200°F)
• Good UV resistance
• Designed for single coat application, may be used in two coats if so specified or on complex structures

Application

Substrate conditions of carbon steel for insulated and non-insulated service

Must be free of oil, dirt, grease and all other contaminants, especially salts. Round off all rough welds and sharp edges. Remove weld spatter. Recommended dry abrasive blast cleaning to SSPC-SP 6, “Commercial Blast” (ISO-Sa 2) with a 25 to 50 μm (1.0 to 2.0 mils) profile

Substrate conditions of stainless steel for insulated and non-insulated service

Must be free of oil, dirt, grease and all other contaminants, especially salts. Round off all rough welds and sharp edges. Remove weld spatter. Small surfaces may be cleaned with a chlorinated-free solvent. Large surfaces may be cleaned utilizing a high- or low pressure wash or steam cleaning with an alkaline detergent (such as Prep 88), followed by a freshwater rinse. Water used should be potable grade or better and should be checked to assure minimal salt content. Do not use any chemical
additives in the rinse water.

Note: Do not use chlorinated solvents on stainless steel surfaces

Substrate temperature and application conditions

Substrate temperature during application should be between 10°C (50°F) and 66°C (151°F). Substrate temperature during application should be at least 3°C (5°F) above dew point. Relative humidity during curing should be above 20% and below 90%. 

Apply via brush, roller, airless or air assisted spray as per data sheet recommendations.
