ABSTRACT:
The metal adhesion and heat and water resistance of conventional neoprene latex adhesives are improved by the addition thereto of a polyamine and an epoxy resin wherein for every 100 parts by weight of dry neoprene, the epoxy is added in an amount of 10-40 parts and the amine is added in an amount sufficient to provide 50-150% of the stoichiometric amount required to cure the epoxy.
