seen with a wax overdraga intended for underwater surface, whereby the wax contains one or several biocides permanent of a metallsalt of a polymer acid or a polyionen

摘要

Underwater surfaces are protected against weed and/or shell growth with a wax coating containing one or more biocides effective against weed and/or shell growth when dissolved or dispersed in wax. The biocides are preferably sea-water insoluble and may be fresh water soluble also. They are preferably thermally stable up to 150 DEG C and soluble in wax. Suitable biocides are Cu, Zn, Ni, Co, Mn or Sn salts of carboxylic acids or polyacrylic acids, or organic compounds having an active structure containing S, Cl, N or O.
