FAQ
What is the difference between MBT and MBTS?MBTS is the disulfide of MBT. MBT is faster but has short processing safety; MBTS processes more safely. MBTS is mostly preferred in general-purpose compounds.
Why is MBT used together with a guanidine?Basic secondary accelerators such as DPG activate thiazoles. This synergistic system gives a shorter cure time and a higher crosslink density.
