These results indicate that the electrical resistivity increases with addition of 2-mercaptobenzimidazole, 2- mercaptobenzothiazole, and thioglycolic acid.

The effects of 3 mL/L of 2- mercaptobenzimidazole (Fig 5), 2 mL/L of 2- mercaptobenzothiazole (Fig 6), and, 4 mL/L of thioglycolic acid (Fig 7) were evaluated.

Therefore, allergic contact dermatitis associated with accelerators such as dithiocarbamates, thiurams or mercaptobenzothiazole can be avoided.

Biological evaluation and chemical characterization of photochemically crosslinked surgical gloves

Cure systems with primary accelerators such as mercaptobenzothiazole disulfide (MBTS) or sulfenamides such as tert-Butyl-2-benzothiazole sulfenamide (TBBS) have been used to address such requirements.

Such molecules are effective secondary accelerators for zinc mercaptobenzothiazole, and the compounds can show resistance to copper staining and improved ozone resistance of natural rubber latex film.
