Abstract
There is disclosed an improved method for open steam curing of mineral-loaded elastomers. It has been discovered that use of a vulcanization agent comprising a mixture of an alkyl phenol disulfide and a guanidine compound provides a synergistic curing system that is superior over the use of either component alone. The improved curing system of the present invention is particularly suited for the open steam curing of mineral-loaded chlorobutyl compounds. The cure system may be used in addition to zinc oxide and results in excellent states of cure as determined by tensile elongation and hardness measurements.
