Abstract

The present invention provides a binary process for manufacturing dipped latex product. The binary process disclosed herein eliminates the influence of any level of pre-vulcanization on the outcome of the dipping process whether using natural or synthetic latex. The binary process includes preparing a first latex mixture Formulation A comprising latex, one or accelerators, and one or more surfactants, and preparing a second latex mixture Formulation B comprising latex, one or more curing agents, and one or more surfactants. Further, dipping one or more formers into the Formulation A and B separately in order to form a plurality of coatings/layers of the Formulation A and B, and later on curing the plurality of coatings/layers on the formers to form the dipped latex products, which can be a condom, glove, balloon, catheter, finger cot, surgical tubing, baby bottle nipple or dental dam.
