Product Description
CAPAC-ZMBT, (CAS No. 136-23-2), 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.

Name: Zinc 2-mercaptobenzothiazole(CAS No. 155-04-4 ),

CAPAC-ZMBT in combination with CAPAC-ZDEC is mainly used in NR / Synthetic Rubber Latex compounds for the manufacture of Latex Thread, Latex Foam and other Latex based products. CAPAC-ZMBT in combination with basic secondary accelerators is used in Dry Rubber compounds for the manufacture of Footwear products, Hot air cured products, molded and extruded goods etc

Compounding Information
CAPAC-ZMBT is a Semi ultra-fast accelerator for NR, SBR, NBR, BR and other diene rubbers. The critical cure temperature of CAPAC-ZMBT is approx. 120° C and hence the dry rubber / NR latex based compounds are vulcanized quickly at 125° C. The state of cure developed by CAPAC-ZMBT is slightly lower than CAPAC-ZMBT; However, the scorch safety is much longer and hence CAPAC-ZMBT can be used in place of CAPAC-ZMBT or scorch control.
-CAPAC-ZMBT is mainly used NR & Synthetic Rubber Latex compounds along with CAPAC-ZDEC / CAPAC-ZDBC to improve the state of cure. CAPAC-ZMBT also improves the aging characteristics of NR Latex based vulcanizates.
-CAPAC-ZMBT does not influence the stability of latex compounds.

-CAPAC-ZMBT readily disperses in water in the presence of commonly used dispersing agents (e. G. Sodium salt of polymerized alkyl naphthalene sulfonic acid) and is usually used as a 50% dispersion in water for latex compounding applications. CAPAC-ZMBT has a sensitizing effect on NR Latex due to its thixotropic nature and this property favors NR latex foaming for the production of Latex Foam Products. The latex compounds in which this property is not desired; The thixotropic effect can be overcome by stirring.
-When used for compounding of Latex Foam manufacture; CAPAC-ZMBT and CAPAC-ZMBT combinations give Latex Foam products with high compression modulus and vulcanizable at 110° C. One can reduce the dosage of Zinc Oxide in Latex Foam compounds for optimization / adjustments in gelation periods.

-Normal dosages of Zinc Oxide and Stearic Acid are necessary when CAPAC-ZMBT is used for dry rubber compounding. However; Dosage of Zinc Oxide can be reduced considerably for certain specific applications.
-CAPAC-ZMBT can be activated by small dosages of basic accelerators such as TMTM, DPG, TMTD, ZDEC etc. Or even by other basic compounding materials. If required; Common acidic retarders or Pilgard PVI can be used to delay the on-set of cure.
-High Accelerator-Low Sulfur cure systems based on CAPAC-ZMBT offer excellent heat resistance to NR vulcanizates. CAPAC-ZMBT also acts as an effective retarder for Sulfur cure systems based on Thiurams & Dithiocarbamates as primary accelerators.
