  • Patent number: 12275862
    Abstract: Embodiments herein relate to a non-aqueous liquid foul release coating composition for controlling aqueous biofouling on man-made objects comprising a moisture curable polysiloxane comprising repeating units of according to formula (I) as described in the application and at least one terminal or pendant group of according to formula (II) as described in the application; and at least one of a marine biocide or a non-volatile component comprising units selected from hydrocarbyl, heterocarbyl, halocarbyl, ether, ester, amide, ketone, siloxane, urethane or urea groups. Embodiments herein further relate to a substrate coated with such coating composition and to processes of use of such coating compositions to control aquatic biofouling of a man-made object.

  • Patent number: 12234378
    Abstract: The present disclosure relates to a tie-coat composition comprising one or more binder polymers obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, wherein the tie-coat composition provides a tie-coat with good dry adhesion, freshwater adhesion and saltwater adhesion to topcoats based on resins with condensable silane groups such as polydiorganosiloxane resins with hydrolysable groups or organic resins with terminal and/or pendant alkoxysilyl groups. The present disclosure further relates to a process for controlling aquatic fouling on a surface of a man-made object comprising applying such tie-coat composition and a topcoat composition, and to a substrate coated with a tie-coat layer deposited from such tie-coat composition and a topcoat layer.

  • Publication number: 20210277256
    Abstract: The invention relates to a tie-coat composition comprising one or more binder polymers obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, the one or more binder polymers comprising pendant curable alkoxysilyl functional groups of general formula (I) —X-L-Si(R1)n(OR2)(3-n) (I) wherein L is a hydrocarbon linker group having 1 to 20 carbon atoms, X is a heteroatom other than a sulphur atom, n is 0, 1, or 2; R1 is an alkyl radical with 1 to 20 carbon atoms, R2 is an alkyl radical with 1 to 20 carbon atoms or an alkylalkoxy radical with 2 to 20 carbon atoms, wherein in at least 5 mole % of the curable alkoxysilyl functional groups comprised in the one or more binder polymers the hydrocarbon linker group L is a methyldiyl group (L1) and in at least 5 mole % of the curable alkoxysilyl functional groups comprised in the one or more binder polymers the hydrocarbon linker group L is a hydrocarbon group having 2 to 20 carbon atoms (L2), wherein the tie-coat composition does not comprise a cros
