International Interzone 505 is a high solids, low VOC, high build epoxy primer/intermediate or finish coat. Reinforced with chemically resistant high aspect ratio glass flake for enhanced durability and corrosion resistance.
International Interzone 505 is formulated for the protection of steelwork in all corrosive environments including splash zone areas on offshore structures, under deck, decks and above water areas, pilings, pulp and paper mills, bridges and chemical plants.
International Interzone 505 provides excellent long term, anti-corrosive and anti-abrasion protection in both new construction and maintenance situations. Suitable as part of a non-slip deck system in conjunction with appropriate aggregate.
Approved for use as on Highways, Network Rail New Works and London Underground New Works.
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 505, 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.
Ultra High Pressure Hydroblasting / Abrasive Wet Blasting
May be applied to surfaces prepared to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 which have flash rusted to no worse than Grade HB2½M (refer to International Hydroblasting Standards) or Grade SB2½M (refer to International Slurry Blasting Standards). It is also possible to apply to damp surfaces in some circumstances. Further information is available from International Protective Coatings.
