Chartek 7 achieves key Norsok fire protection standard

11 October 2011

International Paint’s epoxy passive fire protection coating Chartek 7, has achieved the protective coating standard Norsok M501 Revision 5, even without a top-coat. M501 Revision 5 is a key measure for determining the effect of weathering on the anticorrosive properties of fire protection coating systems in the rigorous environments found at coastal and offshore locations.
Chartek 7 is the only jet-fire certified product on the market to achieve the standard. Most importantly the ‘pull off’ test after environmental cycling, shown to be a good indicator of the integrity of the film after weathering, was found to be 5MPa, greater than 50% of the initial value.
"For most of its life, epoxy passive fire protection (PFP) acts primarily as a barrier coat to prevent corrosion of the steel substrate. In a fire, however, the PFP has to insulate the steel from reaching critical failure temperatures. The pull off test shows that environmental weathering does not cause Chartek 7 to lose its integrity and so affect its fire protection ability,” said Robin Wade, International Paint’s technical marketing manager for fire protection.
"The above testing will give asset owners confidence that structures coated with Chartek 7 will be protected from both corrosion and fire, even in harsh offshore and coastal environments, without reliance on a top-coat,” Wade continued.
Chartek 7 recently received certification from Lloyds Register and DNV (Det Norske Veritas) and ABS (American Bureau of Shipping) in accordance with the new ISO 22899 standard for hydrocarbon jet fire durations up to three hours. Chartek 7 was the first fire protection coating to achieve this approval with DNV.
