Abstract
The present application describes novel antifouling coating compositions comprising carbon-based hydrolysable polymers of ethylenically unsaturated monomers of which some include cyclic carbonates or cyclic ethers, e.g. (2,2-dimethyl-1,3-dioxolan-4-yl)methyl (meth)acrylate (IPGA/IPGMA), isopropylidene glycerol ethoxylated acrylate (iPGEOA), isopropylidene glycerol ethoxylated methacrylate (iPGEOMA) and (2-oxo-1,3-dioxolan-4-yl)methyl (meth)acrylate (GCA/GCMA), and their use in antifouling coating compositions. Novel polymers are also described.
Claims25
An antifouling coating composition comprising an erodible binder system,
- wherein said binder system comprises a polymer of ethylenically unsaturated monomers, said monomers including at least one monomer of the general formula (I):
- wherein in is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), wherein R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl, and
- wherein said erodible binder system comprises one or more further binder components.
An antifouling coat comprising an erodible binder system, wherein said binder system comprises a polymer of ethylenically unsaturated monomers, said monomers including at least one monomer of the general formula (I):
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), wherein R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl,
- wherein said erodible binder system comprises:
- one or more further binder components;
- and
- one or more pigments and fillers.
A method for improving the antifouling properties of a coating composition comprising an erodible binder system comprising the step of incorporating as a co-binder one or more polymer(s) of ethylenically unsaturated monomers into said coating composition, said monomers including at least one monomer of the general formula (I):
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), wherein R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl, and
- wherein said erodible binder system, comprises one or more further binder components.
An antifouling coating composition comprising a polymer of ethylenically unsaturated monomers and a rosin, wherein said monomers includes at least one monomer of the general formula (I):
- wherein m is 0-50, n is 1-3, R1 is selected from hydrogen and methyl, and X is selected from >C═O or >C(R2)(R3), where R2 and R3 are independently selected from hydrogen, C1-20-alkyl and aryl.
