    Abstract: An erodible antifouling coating composition for application, for example, to ship's hulls to potentially prevent the adhesion and build-up of fouling agents on the hull is described. The coating composition includes 10 to 60% by solids weight of an erodible binder system that excludes a triorgano tin based binder; one or more antifouling agents; and 1 to 10% solids weight of a mixture of silicone oils, wherein the mixture includes a first and second silicone oil each comprising alkyl and aryl groups attached to silicone in a different ratio. A process for producing the composition, a substrate coated with the composition, and a process of coating a substrate with the composition are also described.

    Abstract: The present invention relates to a process for repairing a coating film by applying an adhesion primer comprising a hydroxy-functional (meth)acrylate resin, a hydroxy-functional epoxy resin, a polyisocyanate, and an epoxy-functional organosilane directly to a substrate that is a substrate body with an original coating that has defects, to form an adhesion-promoting film and, applying at least one further layer of coating to the resultant adhesion-promoting film. The invention further relates to the use of the adhesion primer to improve the adherence of a further coating layer to such substrate, preferably to a substrate with a substrate body of glass fiber-reinforced unsaturated polyester resin, of glass fiber-reinforced epoxy resin, or of glass fiber-reinforced vinyl ester resin, wherein the further coating layer preferably is a polyurethane-based coating. The present invention further relates to a substrate coated with a coating film that has been repaired according to such a process.

    Abstract: Curable composition comprising a stable, water dispersible, curable polymer containing a sterically hindered alkoxylated silane group at 0.1 to 75 weight percent of the total composition; a water dispersible or water soluble, hydrolytically stable organotin catalyst, at 0.1 to 10 weight percent of the total composition; and water at 99.8 to 24.9 weight percent of the total composition are taught herein. These compositions are useful as adhesives, sealants and paints. The compositions have improved properties including solvent resistance, adhesion, hardness, abrasion resistance and mar resistance. Particular catalysts for use herein include mercaptoalcohol, mercaptide and sulfide forms of diorganotins having either a Sn--S or Sn.dbd.S bond, and include dibutyltin dimercaptide and dibutyltin bis(1-thioglycerol).
