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.
