| Accelerator ZMBT |
 |
ZMBT is a versatile semi-ultra accelerator of the mercapto class.
It is activated by all basic accelerators, thiurams and dithiocarbamates.
ZMBT can also be used to activate basic accelerators and when added in small amounts will extend the processing safety of thiuram and dithiocarbamate cures without discoloration.
Delayed action in cure can also be obtained when using Retarder BA with ZMBT or when MBTS is the secondary accelerator.
The use of 2-4 phr of ZMBT with 0.5 - 0.05 phr thiuram and low sulfur exhibits outstanding resistance to heat.
Normal use in mechanical goods would be 0.8 - 1.2 phr. ZMBT, 0.01 - 0.5 phr of a secondary accelerator with normal sulfur.
ZMBT-OT is the reduced dusting version containing a 2% oil treatment. |
