Beiträge zur galvanisierung von polymeren, 11. Metallisierung von mischungen aus epoxidharzen und acrylnitril-butadien-copolymeren

The metallization of mixtures containing epoxy resins and acrylonitrile-butadiene copolymers depends on taking the suitable ratio of components and on the hardener, which was brought to reaction with the epoxy prepolymer in presence of the copolymer. Using triethylenetetramine as curing agent the highest values of peel strength have been reached and have been increased up to 150 N/25 mm by short-time-treatment with ozone. Longer ozonization times lead to lower values of peel strength and impairment of the material. Caverns occur only in mixtures which are rich on epoxy resin, and increase in size with increasing time of ozone treatment. These samples have relatively low values of peel strength.
