ABSTRACT:
This invention relates to compositions comprising a polymer base incorporating antifouling compositions suitable for use in aquaculture, marine and architectural systems as paints, structures or coatings. In particular, the present invention relates to a polymer based coating incorporating a biocidal antifouling composition suitable for use with aquaculture equipment. The present invention provides polyethylene compositions and latex compounds which may comprise at least one environmentally benign phytochemicals suitable for use in preventing the colonization of a treated surface by a variety of biological species. The compositions of the invention may further comprise control release agents such as, for example, micro-encapsulation of the phytochemicals to maintain sustained and prolonged release of the biocidal agents at the treated surface.
