A water-based adhesive that is delivered in a stable one-part system comprises (i) an emulsion of a vinyl and/or acrylic polymer; (ii) a water-dispersed ionic or nonionic polyurethane; (iii) a polyethylenimine; and (iv) a carbodiimide.

Water-based laminating adhesives

A process for flocking cured or uncured elastomeric substrates comprising the steps of applying to the substrate an aqueous adhesive comprising 10 to 100% (dry weight) of an alkaline dispersion of an ethylene carboxylic acid copolymer and 0 to 90% of an aqueous elastomeric dispersion; electrostatically applying flocking fibers thereto; and drying the thus flocked substrate.

Process for flocking EDPM substrates

Conventional carboxylated neoprene latex adhesives are improved with respect to their metal adhesion, heat and water resistance and bonding range by the addition thereto of an epoxy resin, preferably an epoxy resin prepared by the reaction of para-aminophenol with epichlorohydrin.

Neoprene latex contact adhesives

The metal adhesion and heat and water resistance of conventional neoprene latex adhesives are improved by the addition thereto of a polyfunctional amine 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.
