DEF

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.

CONT

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.

OBS

"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.

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.

Resin impression tray material is a device intended for use in a two-step dental mold fabricating process. The device consists of a resin material, such as methyl methacrylate, and is used to form a custom impression tray for use in cases in which a preformed impression tray is not suitable, such as the fabrication of crowns, bridges, or full dentures. A preliminary plaster or stone model of the patient's teeth and gums is made. The resin impression tray material is applied to this preliminary study model to form a custom tray. This tray is then filled with impression material and inserted into the patient's mouth to make an impression, from which a final, more precise, model of the patient's mouth is cast.
