Jotun Epoxy HR
Jotun Epoxy HR is a two component polyamine cured phenolic / novolac epoxy coating, formulated as corrosion protection for surfaces operating at elevated temperatures where long corrosion protection is desired. Suitable for insulated and non insulated surfaces.
Best Uses
Designed as a heat-resistant coating, Jotun Epoxy HR is resistant to low temperatures down to -196 °C and high temperatures up to 205 °C continuously. Suitable for use on insulated and non-insulated surfaces. This product may be used as a primer, mid coat or finish coat. Suitable for properly prepared carbon steel, galvanised steel, stainless steel and aluminium substrates. It can be applied on hot substrates up to 150°C. Please refer to the application guide for more detailed information.
Jotun Epoxy HR will offer proper corrosion protection at ambient conditions during construction and shut-down periods. The product passes the standard tests used for qualifying coatings preventing corrosion under insulation (CUI).
Heat resistance
- Carbon steel: Continuous: 205°C
- Stainless steel: Continuous: 205°C
- Alloyed steel (P91): Continuous: 205°C
The continuous operational temperature limits are based on the substrate’s heat-resistant properties.
Application
Preparation
- Carbon steel - Sa 2½ (ISO 8501-1)
- Stainless steel - Abrasive blast cleaning to achieve a surface profile using non-metallic abrasive media which is suitable to achieve a sharp and angular surface profile
- Aluminium - Abrasive blast cleaning to achieve a surface profile using non-metallic abrasive media which is suitable to achieve a sharp and angular surface profile
- Galvanised Steel - Sweep blast-cleaning using non-metallic abrasive leaving a clean, rough and even pattern
- Shop Primed Steel - Sa 2½ (ISO 8501-1)
- Coated surfaces Clean, dry and undamaged compatible coating
Application
Jotun Epoxy HR can be applied by airless spray. Use a brush for stripe coating and small areas. Care must be taken to achieve the specified dry film thickness. Follow Application Guide sheet.
