International Intertherm 2205

International Intertherm 2205 is formulated as a high performance repair solution for use in aggressive, Corrosion Under Insulation (CUI) environments. It generates cost savings through improved performance and enhanced productivity.

Best Uses

Intertherm 2205 is designed for application to steel surfaces that are operating at elevated temperatures of between 60ºC and 205ºC, in facilities where downtime needs to be reduced by continuing operations during maintenance periods.

Also, for the maintenance and repair of process pipe, valves and vessels in highly corrosive, CX environments, which operate at temperatures up to 230ºC and in thermal cyclic conditions.

Intertherm 2205 is suitable for use on either insulated or uninsulated surfaces.

Application

The recommended application method for this product is Brush or Roller.

Steel Substrates
Intertherm 2205 has been designed specifically with maintenance considerations in mind and so can be applied over a range of surface preparation standards, for hand tooled, power tooled or abrasive blast cleaned methods, including St2, St3, Sa2, Sa2½ (ISO8501-1) and SP2, SP3, SP11, SP6, SP10 (SSPC).

Ensure that all surfaces are clean, dry and free from contamination. Prior to paint
application all surfaces should be assessed and treated in accordance with ISO 8504:2000.

For hand or power tool preparation methods: areas which cannot be prepared adequately by chipping or needle gun, or where there is no pre-existing surface profile present, should be spot blasted to a minimum standard of ISO8501-1, Sa2/SSPC-SP6. Typically, this would apply to a C or D grade rusting in this standard.

Stainless Steel
Intertherm 2205 may be applied to stainless steel substrates. Surface should be clean, degreased and either abrasive blast cleaned or power tool cleaned ensuring a 35-50µm surface profile is achieved.

Aged Coatings
Intertherm 2205 is suitable for overlap onto most aged coating systems, including residual inorganic zinc silicate coatings. Remove all loose, flaking or poorly adhering coatings back to a firm edge and prepare the bare steel as above, without polishing the surface. Aged epoxy coatings and any glossy areas should be abraded. All areas to be coated should be clean, dry and free of oil or
grease prior to painting.

System Compatibility

Intertherm 2205 will normally be applied direct to metal, but is compatible for overlap on the following coatings:

• Interbond 2340UPC
• Interplus 256
• Intertherm 228HS
