Select Accelerators for Rubbers. Edward M. Petrie. Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. Selection of an accelerator will depend on the specific vulcanizing system and curing properties.

The most important accelerator of the group, MBT, was introduced in and its subsequent impact on the rubber industry has been remarkable. The zinc salt is rarely used in dry compounding but is commonly used in the natural rubber latex industry, particularly in the manufacture of elastic thread.

The most common commercial thiazoles are 2-mercaptobenzothiazole (MBT) and bis-(2-benzothiazol) disulphide (MBTS) and eventually zinc salt of 2-mercaptobenzothiazole (ZMBT). . They have improved scorch safety and allow for cure at quite high temperatures with short curing time and broad vulcanization plateau but relatively low crosslink density.
A popular accelerator is N-tert-butyl-2-benzothiazolesulfenamide (BBTS). Besides giving a longer scorch delay, BBTS gives higher modulus than CBTS, so dosage can possibly be reduced 10%. Very frequently the sulfenamides are used with secondary accelerators like TMTD.
