Document Type and Number:
Japanese Patent JP7308918
Kind Code:
B2
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 crosslinking agent. The invention 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.
