Superiority:

Abstract
CAPAC-TIBTD (CAS No. 3064-73-1), is used as a fast curing primary accelerator or as a secondary accelerator.

Identification
Name: Isobutyl thiuram disulfide(CAS No. 3064-73-1),
CAS Registry Number: 3064-73-1
EINECS: 221-312-5

Application
CAPAC-TiBTD is a fast curing primary or secondary accelerator in NR, SBR and NBR applications. Can take the place of TMTD, TETD.
- In mercaptan modified polychloroprene vulcanized with ETUCAPAC-TiBTD acts as a scorch Retarder without affecting the cure speed.
-CAPAC-TiBTD has longer scorch times when compared to TMTD.
-CAPAC-TiBTD is non-staining and non-discoloring.
-CAPAC-TiBTD is regulated for use in articles in contact with food as specified under BfR Recommendation XXI, Category 4. CAPAC-TiBTD is not regulated for use in FDA food contact applications.



Compounding Information
In NR formulations CAPAC-TiBTD 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-TiBTD) to compensate for the reduced amount of sulfur donated from CAPAC-TiBTD as compared to TMTD. The same trend can be observed in SBR and NBR, at a somewhat reduced level.
