Accelerator MBTS & Perkacit MBTS – Wellt MBTS
Accelerator MBTS & Perkacit MBTS – Wellt MBTS give flat, moderately fast cures in nature and synthetic rubber. Also used in a wide range of general-purpose rubbers. Non-staining/non-discoloring in “white” stock; act as a plasticizer/retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Exhibits better scorch safety than Wellt MBTS.
