Curing system for polyacrylate rubbers

摘要

Compositions containing polyacrylate rubbers having dual curing sites are cured using an improved curing system comprising an alkali metal of a long chain carboxylic acid, a tertiary amine having a two methyl groups and a longer chain alkyl group, and a disubstituted urea. The compositions are shelf stable, have a high degree of scorch safety and cure rapidly at curing temperatures without adversely affecting the compression set of the cured article.
