Title:
SELF-POLISHING ANTIFOULING PAINT
Document Type and Number:
WIPO Patent Application WO2003070832
Kind Code:
A3
Abstract:
Antifouling paint which after application to a surface forms a self-polishing, antifouling coating, comprising a binder with the following polymers A, B and C: A) a copolymer wherein the repeating units correspond to a) a monomer defined by the structure I: in which X is H or CH3, Y is H or optionally an esterified COON-group, R1, R2, R3, R4 and R5 are independently selected from substituted or un-substituted C 1-20 alkyl, C 1-20 aryl, C 1-20 alkoxy or C 1-20 aryloxy, n = 0 or an integer which is 1 or higher b) one or more ethylenically unsaturated monomers; B) a homo- or co-polymer in which the repeating units correspond to one ore more types of ethylenically unsaturated monomers, at least one type having a side chain that ends in a group of formula II in which R6 is selected from substituted or un-substituted C 1-20 alkyl or C 1-20 aryl, Y is -C(=0)- or -0-; the polymer of B) being incompatible with the polymer of A); and also other desired paint components; and optionally !) 0 homo- or copolymer in which the repeating units correspond to one or more types of ethylenically unsaturated monomers, at least one type having 0 side chain ending in 0 group of formula III wherein R7 is substituted or un-substituted ! 1-20 alkyl >3 ! 1-20 aryl, # is -C(=O)- or -0-. The antifouling coating has improved mechanical properties and results in 0 reduced residual layer upon polishing.
