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.

International Interzone 954 is the trusted industry solution for protecting and maintaining structures operating in the most severe environments. A unique blend of properties gives Interzone 954 long term performance in environments that combine a high potential for mechanical damage, chemical attack, atmospheric corrosion and immersion conditions. This versatility makes Interzone 954 the all round heavy duty coating.

Intended Uses

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

Features & Benefits

• A high film build, high solids, abrasion resistant epoxy
• Ideal for single coat application over hydroblasted surfaces (HB2) with tolerance to damp surfaces during application
• Suitable for exposure to tidal sea water just 30 minutes after application (at 20ºC [70ºF])
• Resistant to a wide range of chemicals
• Excellent compatibility with sacrificial and impressed current cathodic protection systems
• Approved to NORSOK M501 for decks (System 4), splashzone and submerged areas (System 7)
• Available in a wide range of colours

International Interzone 954 has been protecting steel in severe environments for over 25 years. With its extensive track record it has gained the industry’s trust as a unique, long term coating solution for the most challenging maintenance situations. Originally designed for the demanding protection of offshore oil and gas structures, Interzone 954’s unique blend of properties has also proven itself in a wide range of new construction applications in the mining and offshore wind power markets.

What makes International Interzone 954 a true all round solution is its ability to provide high build protection in a single coat (typically 500μm [20 mils]). Combined with its surface tolerance and early water resistance this means the impact of the painting process can be minimized allowing rapid return to service and significantly reducing downtime and labour costs compared to a standard two coat epoxy system.

International Interzone 954 offers a combination of properties meeting the challenges of protecting and maintaining structures in severe environments:

• High surface tolerance allows application over hydroblasted surfaces (HB2), even if still damp, as well as power tool and hand prepared steel surfaces (St3) for atmospheric use, this saves time and money on surface preparation
• Early resistance to tidal water movement just 30 minutes after application (at 20ºC [70ºF]), which is ideal for carrying out maintenance in splash zones or on jetty structures
• High impact and abrasion resistance, preventing corrosion caused by mechanical damage through maintaining an intact protective barrier
• Full immersion resistance to a number of aggressive chemicals such as 50% sodium hydroxide and 5% copper sulphate and good general splash and spill resistance to an even wider chemical range, including sulphuric acid, propanol, gasoline and sodium hydroxide

Its corrosion performance, versatility, and time saving value make Interzone 954 the perfect choice for protecting and maintaining a vast range of applications in the offshore, chemical and mining industries, including:

• Jetties and wharfs
• Helicopter decks and walkways when combined with a suitable aggregate
• Oil and gas platform jackets and offshore wind tower foundations
• Coal thickener tank internals and processing vessels
• Structural steel in wet, corrosive areas

*International Interzone 954 can be used as a non-skid deck system by modification with addition of GMA132 (crushed flint) or GPA900 (bauxite) aggregate. Application should then be to a suitably primed surface. Typical thicknesses will be between 500-1,000 microns (20-40 mils). Preferred application is by a suitable large tip hopper gun (e.g. Sagola 429 or Air texture gun fitted with a 5-10 mm nozzle). Trowel or roller can be used for small areas. Alternatively, a broadcast method of application can be used.
