Anti-fouling self-polishable paints
First Claim
1. Anti-fouling self-polishable paints intended to be applied on an object at least partially submersed, comprising at least one of organic solvents, colouring pigment, wetting agents, dispersing agents and neutralising agents, the paints further comprising:
- mass 5 to 60% of at least two polymers (I) of an alkyl polyacrylate or alkyl polymethacrylate family, each of the at least two polymers (I) comprising carboxylic functions and having a very different acid index;
mass 0.1 to 50% of at least one polyaminated compound (II), the compound (II) being chemically linked with the at least two polymers (I);
mass 0.1 to 60% of at least one organometallic compound (III) comprising at least one of zinc, iron, manganese or cobalt, the organometallic compound (III) having a biocide character; and
mass 0 to 30% of powdered hydrophobe polymers (IV).

Abstract
The invention relates to anti-fouling self-polishable paints intended to bepplied on an object at least partially submersed, notably on surface ships or submarine hulls, and containing standard constituents of the paints such as organic solvents, coloring pigment, wetting agents, dispersing agents or neutralizing agents.
These paints are characterized in that they comprise:
mass 5 to 60% of at least two polymers or copolymers (I) of the alkyl polyacrylates or alkyl polymethacrylate family comprising carboxylic functions, having molecular weights ranging from 15,000 to 100,000 g.mol-1, each polymer having a very different acid index,
mass 0.1 to 50% of at least one polyaminated compound (II) reacting to polymers (I),
mass 0.1 to 60% of at least one organometallic compound derived from zinc, iron, manganese or cobalt, with a biocide character (III).
mass 0 to 30% of powdered hydrophobe polymers (IV).

10. Anti-fouling self-polishable paints intended to be applied on an object at least partially submersed, comprising at least one of organic solvents, colouring pigments, wetting agents, dispersing agents and neutralising agents, the paints being in a form of dry film after application on a surface and further comprising:
-
mass 10 to 90% of at least two polymers (I) of an alkyl polyacrylate or alkyl polymethacrylate family, each polymer of the at least two polymers (I) comprising carboxylic functions and having a very different acid index; mass 1 to 50% of at least one polyaminated compound (II), the compound (II) being chemically linked with the at least two polymers (I); mass 1 to 60% of at least one organometallic compound (III) comprising at least one of zinc, iron, manganese or cobalt, the organometallic compound (III) having a biocide character; and mass 0 to 20% of powdered hydrophobe polymers (IV).
