Product Description

International Interzone 954 is a two component, low VOC, high solids, modified epoxy barrier coat designed to give long term protection in a single coat application. Will continue to cure when immersed in water and has excellent cathodic disbondment resistance.

Best Uses

International Interzone 954 is primarily designed for use in offshore splash zone maintenance, where its continued cure under immersed conditions makes it ideal for coping with tidal movements and surges. May be applied to re-oxidised and slightly damp surfaces. Interzone 954 has also found extensive use in a number of other corrosive environments including rail cars, pulp and paper plants, chemical plants, jetties and sluice gates. As part of a non-slip deck system in conjunction with appropriate aggregate.

  • Interzone 954 was originally developed for the severe environments encountered in offshore environments such as those described as C5M and lm2
  • Formulated for barrier corrosion protection via a densely crosslinked binder system combined with a high dry film thickness
  • Excellent resistance to mechanical impact and abrasion encountered in buried environments
  • Excellent resistance to permanently immersed seawater and fresh water environments
  • Splash and spillage resistance to a wide range of chemicals
  • Excellent compatibility with cathodic protection
  • Use as a non slip deck system
  • Suitable for C1, C2, C3, C4, C5-I, C5-M, Im1, Im2, Im3 environments


The performance of this product will depend upon the degree of surface preparation. The surface to be coated must be clean and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Accumulated dirt and soluble salts must be removed. Dry bristle brushing will normally be adequate for accumulated dirt. Soluble salts should be removed by fresh water washing. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning: Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Interzone 954, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A surface profile of 50-75 microns (2-3 mils) is recommended.

Hand or Power Tool Preparation: Hand or power tool clean to a minimum St3 (ISO 8501-1:2007) or SSPC-SP3 for atmospheric use only. Note, all scale must be removed and areas which cannot be prepared adequately by chipping or needle gun should be spot blasted to a minimum standard of Sa2 (ISO 8501-1:2007) or SSPC-SP6. Typically this would apply to C or D grade rusting in this standard.

Ultra High Pressure Hydroblasting / Abrasive Wet Blasting: May be applied to surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC-SP6 which have flash rusted to no worse than Grade HB2M (refer to International Hydro-blasting Standards). It is also possible to apply to damp surfaces in some circumstances. Further information is available from International Protective Coatings.

Aged Coatings
Interzone 954 is suitable for overcoating some sound intact aged coatings. To ensure compatibility, application and evaluation of a test patch is required.
