THE END OF GUANIDINES?AN ALTERNATIVE CURE SYSTEIVI FORPOLYCHLOROPRENE LATEX

摘要

Over the past several years, rumors have continued to swirl that guanidine accelerators, specifically 1,3-diphenylguanidine (DPG) and N,N'-di-ortho-tolylguanidine (DOTG) may no longer be allowed to be sold in Europe due to prospective REACh regulations. These products are commonly used in the cure systems for polychloroprene latex. Since the future status of these accelerators is in doubt, it is important to develop new cure systems now. This paper investigates potential alternative cure systems for use in polychloroprene latex.
