International Paint introduced Intersmooth 7465Si SPC and Interswift 6900Si silyl acrylate antifouling coatings. The company reports that it is first to offer both copper acrylate and silyl acrylate antifouling coatings within a comprehensive range of fouling control technologies.
In 2006, International Paint patented silyl acrylate technology for use with products of <400g/l VOC (volatile organic compounds). This technology is incorporated into Intersmooth 7465Si SPC and Interswift 6900Si and allows delivery of the same performance as its current Intersmooth 7460/5HS SPC and Interswift 6800HS copper acrylate antifouling coatings. Both new silyl products have solvent emission levels of less than 400g/l VOC.
Designed for deep sea vessels at newbuilding and maintenance and repair, Intersmooth 7465Si SPC features 55% volume solids. Reduced overspray helps leads to lower contamination levels in dock and reduced applicator exposure. For the vessel operator, the product delivers predictable, high performance fouling control for up to 90 months and its inherent self-smoothing action potentially reduces fuel use by 4%, cutting operational costs, lowering carbon dioxide emissions and improving vessel operating image.
Interswift 6900Si incorporates patented silyl acrylate polymer technology. Also designed for vessels at newbuilding and maintenance and repair, the product offers 61% volume solids, surface tolerance and in-service periods of up to 60 months with potential fuel savings of 1.5%.
