The abbreviation DOTG stands for the chemical composition N, N’-di-o-tolylguanidine. DOTG is mainly used in the rubber industry as vulcanisation accelerator in acrylate rubbers (ACM, AEM).
During processing and storage hazardous substances can be released from DOTG produced rubber parts. These substances are seen as a potential health risk in the rubber. Elastomer products free of DOTG are also increasingly demanded by the automotive industry.
Although, there is no legal restriction on the application of DOTG, the rubber industry has set itself the goal offering innovative accelerator systems for DOTG free acrylate rubber products.
