Function
ZDBC is a very fast primary or secondary (ultra) accelerator for natural and synthetic rubber. It is also a very rapid accelerator for NR and SBR latices. Additionally it is an antioxidant in rubber adhesive systems.
MAJOR APPLICATIONS AND PROPERTIES
ZDBC is used as secondary ultra accelerator for thiazole and sulfenamide cure systems in general purpose polymers (NR, SBR, IIR, EPDM). It can be used as a primary accelerator in specialty applications as well as in latex.
- In latex applications ZDBC is mainly used in transparent goods and in prevulcanized latex. - An additional application is as an antioxidant in adhesive systems.
ZDBC gives faster cures than ZDEC or ZDMC.
- It should be noted that in the application of ZDBC N-nitrosodibutylamine can be formed by the reaction of dibutylamine, a decomposition product, with nitrosating agents (nitrogen oxides). ZDBC is regulated for use in articles in contact with food as specified under FDA 21 CFR 175.105, 178.2010, 175.300, 177.1210, 177.2600 and under BgVV XXI, Categories 1-4 and "Sonderkategorie".
Compounding Information
In NR latex, when used as a primary accelerator 1 phr of ZDBC with 2.5 phr sulfur is a good starting point.
In EPDM ZDBC has the highest solubility of all dithiocarbamates, offering the lowest blooming effect. An acceptable starting point for a low set non-blooming EPDM compound is ZDBC 2.0, TMTD 0.8, DPTT 0.8 and DTDM 2.0 phr.
In rubber cured in contact with polyester textiles ZDBC is preferably used over other dithiocarbamates.
