摘要： A tough and long-lasting adhesion of polyolefins to metal substrates is realized by means of a process comprising the following four process steps, carried out in succession:(a) mechanical cleaning of the metal surface;(b) treatment of the metal surface with a water-alcohol solution containing at least an alkoxysilane and boric acid;(c) thermal treatment of the surface coming from the (b) step;(d) treatment of the so-treated surface with a polyolefin based composition, containing zeolites and carbon black.
