DOLDER MASSARA has been the market leader when it comes to accelerators for rubber. For decades, we sold products for FLEXSYS (formerly MONSANTO). After these products were no longer available on the market, we carefully selected new supply sources to satisfy our customers’ requirements. These were supposed to allow us to maintain equivalent quality standards at moderate prices. Subsequently, we developed the DOLDER® ACCELERATOR product series. In this case too, the DOLDER brand guarantees both product quality and a high level of service.
