Mode of action: Isogran® MBT-80C is a semi-ultra, multi-purpose accelerator with a long plateau effect. It provides vulcanizates with good physical properties. In sulphur-free compound Isogran® MBT-80C acts as an anti-scorch agent, in CR compounds as a retarder. Isogran® MBT-80C is activated by basic accelerators such as Aldehyde-amine and Guanidine etc., and by Thiurams and Dithiocarbamates.

Processing: The thermoplastic, fully compatible polymer binder which is combined with special dispersing agents allows quick absorption and excellent dispersion in the polymer. In this way, optimal activity of the effective substance is assured.
