Abstract: The invention relates to anti-fouling self-polishable paints intended to be pplied 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.sup.-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).

Abstract: The invention concerns an anti-corrosive pigmentary composition characterized in that contains zinc 8-hydroxy-quinolate.

Abstract: The invention has as its object multi-coat nonskid surfacings which comprs one or more priming coats and one or more nonskid coats. Each coat comprises a base and a hardener which are mixed before use. The bases contain in particular hydroxylated vinyl terpolymer resins and the hardeners contain a polyisocyanate which reacts with these resins to yield cross-linked polymers known as polyvinyl urethane. The figure represents comparative wear tests. Curves C1 to C3 represent the results measured on known surfacings. Curve C4 represents the results measured on a surfacing according to the invention.One application is the protection of ship decks, particularly flight decks, or offshore oil prospecting platforms.
