binders comprising the association of chlorinated vinyl resins and quaternary ammonium salts are resistant to corrosion , fouling , and organisms in an aqueous medium . the binders are obtained by substituting the chlorines of the polymer with a molecule having a primary or secondary amine function and a tertiary amine function , and then quaternizing the tertiary amine function by an alkyl halide . the binders thus obtained are useful in the production of coatings resistant to fouling and organisms present in an aqueous medium , of bacterial anticorrosion coatings and coatings with fungicidal properties .
