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.

Under the World Trade Organization (WTO), a specific agreement establishing disciplines on the preparation, adoption and application of technical regulations, standards and conformity assessment procedures, that might act as technical barriers to trade.

OBS

Code on Technical Barriers to Trade: ... the Tokyo round had mixed results. It failed to come to grips with the fundamental problems affecting farm trade and also stopped short of providing a new agreement on "safeguards" (emergency import measures). Nevertheless, a series of agreements on non-tariff barriers did emerge from the negotiations, in some cases interpreting existing GATT [General Agreement on Tariffs and Trade] rules, in others breaking entirely new ground. In most cases, only a relatively small number of (mainly industrialized) GATT members subscribed to theses agreements and arrangements. Because they were not accepted by the full GATT membership, they were often informally called "code".

TBT [tributyltin] Alternatives. The most promising alternative appears to be copper-acrylate self-polishing copolymer(SPC) paint which leaches into the water column organic copper biocides in a much more controlled and continuous manner than the release of butyltin residues from TBT paint. The leaching process occurs either by hydrolysis(where the surface layer of the paint film reacts chemically with water leaving a relatively polished surface) or by hydrophylic self depletion(the surface layer is physically removed by the action of the water leaving a fresh surface).

In the clear resin film tests of the zinc acrylate copolymer, molecular weight did not greatly affect the dissolution rate ... As expected from the dissolution rate of the copolymer itself, anti-fouling paints formulated with various zinc acrylate copolymers were found to have erosion rates mainly dependent on function group concentration and hydrophilicity of the resin polymer ... The surface profile of the zinc acrylate anti-fouling, observed by laser microscopy, was also found to be similar to SPC AF [self-polishing anti-fouling] and smoother than other tin-free anti-fouling paints ...

OBS

Are all metal acrylate TBT [tributyltin] free SPC antifoulings the same? No. There are two types of metal acrylate antifoulings. The first type are the copper acrylate... systems. The second type are the zinc acrylate systems. Although the biocides used in these two antifouling systems are essentially the same with the predominant biocide in both systems being copper oxide, copper complexes are more tightly bound and stable in seawater than zinc complexes. In the presence of the copper oxide biocide, zinc acrylate systems(in our experience) may undergo chemical exchange reactions with the copper oxide biocide. Copper acrylate systems do not undergo this exchange. The stability, longevity and performance of the copper acrylate... systems can therefore be expected to be greater than that of typical zinc acrylate deep sea systems.

Two kinds of TBT-containing paints are known. Free-association paint, made by mixing TBT into the paint, dissolves when it contacts water. All of the TBT is leached out from the paint in 12-24 months. In copolymer paint, the TBT is bound to the paint and slowly releases with water movement, and is effective for five to six years...

CONT

Historically, tributyltin(TBT) free-association paints were used. Free association paints are where the active ingredients are dispersed in a resinous matrix and from which they can slowly leach. This type of paint system has been the basis of most traditional antifouling paints... It is difficult to control the rate of release of biocides from a free-association paint system so as to provide a constant leaching level. Paints containing freely associated biocides such as copper compounds and TBT, can give rise to high initial concentrations of biocides in the marine environment.
