Abstract:
Described herein is curable composition comprising a partially halogenated elastomeric gum comprising a plurality of cure sites selected from at least one of iodine, bromine, and nitrile; a silicon-containing compound; a dehydrohalogenation agent; and a peroxide cure system. Upon curing, a silicon-containing superficial layer forms, which can provide good chemical stability, increased durability, non-tackiness, and a matte finish to the cured elastomer.
