Process for making closure sealing compounds and other latex based preparations

摘要

Water based polymeric dispersions, such as closure sealing compounds, which comprise a polymer latex, a resin component and a particulate nonplastic component such as fillers and pigments, can yield improved sealing, adhesion, preservative or decorative films when they are prepared by first suspending the inorganic particulate fillers and pigments in the molten resin components of the formulation, then emulsifying this suspension in water and finally combining the aqueous dispersion obtained with the rubber latex and the other ingredients of the final compound.
