Product Description

International Interzone 954GF is a high solids, low VOC epoxy barrier coat, reinforced with chemically resistant high aspect ratio lamellar glass flake for enhanced durability, abrasion and corrosion protection with excellent cathodic disbondment performance.

Best Uses

International Interzone 954GF is suitable for the protection of steelwork in areas where high abrasion and corrosion resistance are required including splashzone and subsea areas of offshore structures, jetties, decks, bridges, chemical plants, pulp and paper mills, water treatment plants and underground pipework.

International Interzone 954GF has excellent resistance to cathodic disbondment, gives good compatibility with both sacrificial anode and impressed current systems, making Interzone 954GF particularly suitable for the long term protection of sub-sea structures. Can be used as part of a non-slip deck system in conjunction with appropriate aggregate.


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 954GF, 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 Hydroblasting Standards). It is also possible to apply to damp surfaces in some circumstances. Further information is available from International Protective Coatings.

Aged Coatings

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

Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. Once the unit has been mixed it must be used within the working pot life specified. Agitate Base (Part A) with a power agitator. Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.
