<p>Substantially solvent-free water-based adhesives characterized by faster bond strength development and a desirable balance of long term storage stability, high mechanical stability and more rapid drying properties can be prepared from latices of rubbery polymers by using rubbery polymer latices stabilized with emulsifiers which form water-insoluble compounds with zinc and cadmium ions and including in the adhesive formulation a mixture of an ammonium or amine salt gelling agent for the latex, a zinc or cadmium ion donor compound, and ammonia or an ammonia donor compound.</p> |
