Jotun Jotatemp 250
Jotun Jotatemp 250 provides corrosion protection for surfaces operating at extreme temperatures down to -196°C and high temperatures up to 250°C on carbon steel.
Best Uses
Jotun Jotatemp 250 is a two component glass flake reinforced epoxy composite coating. Designed as a heat-resistant coating, it is resistant to low temperatures down to -196°C and high temperatures up to 250°C on carbon steel. Suitable for insulated and non insulated surfaces. Suitable for properly prepared carbon steel, stainless steel, alloyed steel (P91), galvanized steel and aluminium. It can be applied on hot substrates up to 150°C.
Please refer to the application guide for more detailed information.
This product may be used as a primer, mid-coat or finish coat. It 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).
Jotun Jotatemp 250 is designed as corrosion protection for surfaces operating at elevated temperatures where extended protection against corrosion is desired. Particularly suited for use under insulation. Suitable for insulated and non insulated surfaces.
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
The product can be applied by airless spray. Brush is recommended for stripe coating and small areas. Care must be taken to achieve the specified dry film thickness. Follow full application guidance via Application Guide PDF.
