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.
14) kontakt dermatit tanimlayan 26 saglik personeline tiurammiks, merkaptomiks, merkaptobenzotiazol ile yama testi uygulamislardir, birinde thiuram-miks ile pozitif yanit saptanmistir Calismamizda literatur ile uyumlu olarak 3 hastada thiuram mix ile, birinde ek olarak mercaptobenzothiazole
ile pozitiflik saptanmistir.
The slight die-off generally observed in some commercial bellow samples is either due to desiccation of the inoculum as a result of the rubber's high porosity, or the presence of traces of additives, such as mercaptobenzothiazole
, used as an accelerator for the vulcanization process, which exhibit antimicrobial properties.

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.
