摘要

The invention relates to an article with antifouling properties, intended for aquatic uses and, in particular, for marine uses, and to a method for slowing down the growth of aquatic organisms on submersible or semi-subermisible structures.

主权项

1. An article with antifouling properties for use in an aquatic application, comprising:
a) a support b) at least one adhesion-promoting coat deposited on said support, and c) at least one antifouling coat deposited on said adhesion-promoting coat, wherein said antifouling coat is obtained after deposition and curing on contact with atmospheric moisture a composition Z comprising:
(i) at least one organosilicon compound A′ comprising at least two identical or different hydrolyzable and condensable groups, or at least two silanol functions ≡SiOH,(ii) at least one crosslinking agent B′, and(iii) a catalytically effective amount of at least one polycondensation catalyst M which is a zinc complex comprising in its structure a first type of ligand that is a β-diketonate and a second type of ligand that is an amine.
