  • Controlled release compositions
    Patent number: 6676954
    Abstract: Solid compositions containing low water solubility 3-isothiazolone compounds and carbon-based adsorbents that do not rapidly release the 3-isothiazolone when added to a locus to be protected are disclosed. In particular, methods of controlling or inhibiting the growth of marine organisms using the controlled release solid compositions in paints and coatings for marine structures is disclosed.
    Type: Grant
    Filed: March 19, 2001
    Date of Patent: January 13, 2004
    Assignee: Rohm and Haas Company

  • Halopropargyl compounds as marine antifouling agents
    Patent number: 6008244
    Abstract: Disclosed is a method of inhibiting the growth of marine organisms on a marine structure, by applying onto or into the marine structure a halopropargyl quaternary ammonium compound, halopropargyl benzoxazolone compound, or halopropargylhydantoin compound. These compounds may be directly incorporated into the marine structure during manufacture, directly applied to the structure, or applied to the structure by means of a coating.
