Abstract
CAPAC-ZDEC, (CAS No. 14324-55-1), 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 lattices. Additionally it is used as an antioxidant in adhesive systems.
Identification
Name: Zinc bis (diethyldithiocarbamate)(CAS No. 14324-55-1),
CAS Registry Number: 14324-55-1
EINECS: 238-270-9
Application
- CAPAC-ZDEC is a secondary ultra accelerator for general purpose polymers (NR, SBR, IIR and EPDM). It can be used as primary accelerator in some continuous cure applications as well as in latex.
- Furthermore CAPAC-ZDEC is used as an antioxidant in adhesive systems.
- It should be noted that in the application of CAPAC-ZDEC N-nitrosodiethylamine can be formed by the reaction of diethylamine, a decomposition product, with nitrosating agents (nitrogen oxides).
- CAPAC-ZDEC is regulated for use in articles in contact with food as specified under FDA 21 CFR 175.105, 177.2600 and under BfR Recommendation XXI, Categories 1-4 and "Sonderkategorie".
Handling Precautions

Compounding Information
In NR latex 1.0 phr CAPAC-ZDEC together with 2.5 phr sulfur serves as a good starting point when used as a primary accelerator.
A good starting point for foamed applications based on NR or SBR is 1.5 phr CAPAC-ZDEC in combination with 1.0 phr ZMBT and 2.5 phr sulfur.
In NR and SBR CAPAC-ZDEC is generally used at the 0.1 to 0.4 phr level in combination with thiazoles and sulfenamides.
In EPDM rubber applications CAPAC-ZDEC is generally used in blends with other dithiocarbamates in order to minimize bloom; Dosages are determined based on specific application.
