A dried adhesive coating is manufactured by steps of: a) providing a composition comprising a solution of a polymer, wherein at least 1 wt % of said polymer based on the molecular weight Mw are catechol groups, and wherein the concentration of said polymer in said composition is from 0.1 to 250 mg/ml, b) adjusting the pH of the composition to a value from about &#xf3; to about 7, either (i) before applying the composition to the surface to be coated or (ii) after applying the composition to the surface to be coated, c) applying the composition to the surface to be coated to obtain an adhesive coating on at least a part of the surface, and d) drying the coating.

Dryable adhesive coating

This invention relates to the use of a combination of selected substances in paint to prevent the settlement and growth of different biofouling organisms with a reduced negative effect on the ecosystems compared to present methods.

Method and use of nanoparticles to bind biocides in paints

The invention herein relates to the method and use in an antifouling paint that specifically and efficiently impede settlement of for example barnacles on aquatic structures, using imidazole containing compound, such as Medetomidine, bound to a sulfonated, acid sulphate ester, phosphonic acid, carboxylic acid or acid phosphate ester modified polymer backbone such as polystyrene or acrylate polymers. The aim is to employ the biocide-polymer complexes as additives in a self-polishing paint for controlled release purposes.
