International Interzone 101

International Interzone 101 is a two component, solvent free epoxy which can be applied underwater and will cure underwater to give a corrosion and abrasion resistant coating.

Best Uses

International Interzone 101 is formulated as a hand-applied repair compound for application to submerged steelwork and splash zone areas of offshore jackets, piling and other permanently wet areas where conventional coatings can not be used.

Interzone 101 can also be used on glass reinforced materials and concrete and is suitable for use at new construction as well as maintenance.

Application

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-SP10. If oxidation has occurred between blasting and application of Interzone 101, 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 75-100 microns (3-4 mils) is recommended. When applying to bare steel substrates below water or in permanently wet conditions, the surface
should be prepared by power disking with a carborundum disc or by needle gun to achieve a clean, roughened surface in accordance with SSPC-SP11 Power Tool Cleaning.

Only one 12 litre unit should be mixed at a time. To remove contents from their tins, cut both the top and bottom of the tin using a tin opener and push the material out. In cold weather, warming may be necessary. Mixing should be carried out on a large, clean, smooth sheet of steel, tin plate or hardboard using palette knives, scraper blades or trowels. DO NOT ADD WATER OR THINNERS TO THE MIX as this will reduce the strength of the cured composition. The material should be thoroughly
mixed until the separate yellow and blue colours have been completely merged to a bright green colour, free of yellow and blue streaks. Avoid beating air into the mixture and 'fold' the components together.
