Paints consisting of copolymers designed to be smoothed via erosion of their surface as the vessel moves through the water, continually exposing smooth, fresh paint.  4, fiche 1, Anglais, - self%2Dpolishing%20copolymer%20antifouling%20paint

Self-polishing copolymer(SPC) antifoulings release biocides via a hydrolysis reaction of an acrylic polymer with seawater. This is a chemical reaction and only occurs at the surface of the coating. SPC technology combines controlled polishing rate and optimum biocide release with inherent self-smoothing for hull roughness control and maximum fuel efficiency.  3, fiche 1, Anglais, - self%2Dpolishing%20copolymer%20antifouling%20paint

"Controlled solubility copolymers" or "self-polishing copolymers (SPC)" are modern coatings in which, initially for TBT [tributyltin] paints, the biocide was chemically part of the paint matrix or resin, for example the copolymer tributylin methacrylate. When immersed, hydrolysis caused the copolymer to cleave, or hydrolyse, splitting the copolymer into a TBT (the biocide) and an acrylate (the resin) component. The TBT then released and acted as a biocide, the acrylate dissolved to ablate the paint. TBT-free SPCs have now been developed which use copper, zinc or silyl acrylate copolymers.  5, fiche 1, Anglais, - self%2Dpolishing%20copolymer%20antifouling%20paint

Les peintures autopolissantes développées actuellement sont fabriquées à partir de SPC (self-polishing copolymers). Il s'agit de mélanges de méthylméthacrylate de tributylétain. La lixiviation est provoquée par une réaction d'hydrolyse, le composé greffé sur le liant acrylique se libère lentement par hydrolyse dans l'eau.  3, fiche 1, Français, - peinture%20antisalissures%20%C3%A0%20base%20de%20copolym%C3%A8re%20autopolissant

SPC : Self-Polishing Copolymer(SPC) antifoulings release biocides via a hydrolysis reaction of an acrylic polymer with seawater. This is a chemical reaction and only occurs at the surface of the coating. SPC technology combines controlled polishing rate and optimum biocide release with inherent self smoothing for hull roughness control and maximum fuel efficiency. Pioneered by International Paint in the early 1970s, the overall contribution of SPC technology to the fuel efficiency of the global fleet has been significant.  1, fiche 2, Anglais, - self%2Dpolishing%20copolymer

Les produits Shogun 033, Emperor 034 et Platinum 039 de Seajet utilisent tous deux un système perfectionné de copolymères autopolissants (SPC) qui, entre autres avantages, permet une libération minutieusement contrôlée du biocide au contact de l'eau de mer. Le bénéfice de ce procédé est accentué par le mouvement de l'eau sur la coque qui produit une action autopolissante, lissant continuellement la surface et garantissant toujours l'exposition d'une couche nouvelle de biocide à l'environnement. Ce lissage réduit par ailleurs la résistance et permet d'économiser du carburant.  1, fiche 2, Français, - copolym%C3%A8re%20autopolissant

A careful balance is needed between the amount of rosin required to provide sufficient biocide release and the quantity of the other film-forming components used to make the coating tough and durable. As the rosin content increases the binder system becomes softer and more soluble in seawater whereas a low rosin content makes the binder system virtually insoluble and hard. Antifoulings which are softer and more soluble are known as “controlled depletion polymer”(CDP) or soluble matrix antifoulings, whereas the hard types are known as insoluble matrix or “contact leaching” antifoulings.  3, fiche 3, Anglais, - controlled%20depletion%20polymer%20antifouling
