E-Paint Gets USN Authroization
E Paint announced that the U.S. Navy has authorized E Paint SN-1 antifouling paint for use on small boats and craft. Use of E Paint's SN-1 Bottom Coating in Ocean Gray color was specified to meet the Navy's goal to improve overall ship visual camouflage. E Paint SN-1 is the only antifouling coating approved by the Navy for use on small boats as an alternative to silicone fouling release coatings. E Paint products are copper-free replacements for TBT-based antifoulants. E Paint SN-1 is formulated with the booster biocide SEA-NINE® 211 (Rohm and Haas Company), a material that received the first Presidential Green Chemistry Challenge Award in the category for Designing Safer Chemical Products. E Paint SN-1 is EPA approved for commercial use only as an antifouling paint for boat bottoms.
Antifouling Paint Helps USCG Sink Maintenance Costs
The United States Coast Guard (USCG) has reduced maintenance costs by minimizing the time spent on ship bottom refurbishing, with the help of E Paint Company of East Falmouth, Mass. E Paint SN-1 coating provides USCG vessels with well-balanced control over a wide array of common soft and hard fouling species. Vessels coated with E Paint SN-1 solventborne antifouling paint can operate for up to two years before they must be hauled, pressure-washed and repainted. This is longer than is possible with virtually all approved non-metallic biocide antifouling paint. Extending the interval between maintenance significantly reduces vessel downtime.
Rohm and Haas Offers New Literature
Chemicals manufacturer Rohm and Haas Company has published a new bulleting on the use of Sea-Nine 211 marine antifoulant. Sea-Nine employs isothiazolone chemistry as a more environmentally acceptable ingredient in marine plants. The bulleting examines the environmental chemistry and aquatic toxicology of Sea-Nine, and presents a number of data tables to illustrate comparisons between Sea-Nine and tribuyltin. The comparisons show Sea-Nine degrades more rapidly, partitions to sediment more strongly, offers a lower chronic toxicological risk to aquatic organisms and its metabolites are 100,000 times less toxic than the parent compound.
