Abstract
CAPAC-TBZTD, (CAS No. 10591-85-2), is used as a fast curing primary accelerator or as a secondary accelerator. It is used in polychloroprene as a retarder.
Identification
Name: Tetrabenzylthiuram disulfide(CAS No. 10591-85-2 ),
CAS Registry Number: 10591-85-2
EINECS: 404-310-0
Application
-CAPAC-TBzTD has been developed as a safe secondary amine accelerator. N-Nitrosodibenzylamine is not carcinogenic, according to published literature.
-CAPAC-TBzTD is a fast curing primary or secondary accelerator in NR, SBR and NBR applications. In EPDM, CAPAC-TBzTD is a valuable secondary accelerator (booster).
- In mercaptan modified polychloroprene vulcanized with ETUCAPAC-TBzTD acts as a scorch
Retarder without affecting the cure speed.
-CAPAC-TBzTD has longer scorch times when compared to TMTD.
-CAPAC-TBzTD is non-staining and non-discoloring.
-CAPAC-TBzTD is regulated for use in articles in contact with food as specified under BfR Recommendation XXI, Category 4. CAPAC-TBzTD is not regulated for use in FDA food contact applications.
Compounding Information
In NR formulations CAPAC-TBzTD is used at the same level as TMTD (2.5 phr) with a somewhat increased amount of sulfur (0.4 instead of 0.1 phr). In general an extra amount of sulfur is added ( 10% based on the amount of CAPAC-TBzTD) to compensate for the reduced amount of sulfur donated from CAPAC-TBzTD as compared to TMTD. The same trend can be observed in SBR and NBR, at a somewhat reduced level.
