Accelerator ZMBT
ZMBT is a Semi ultra Thiazole Accelerator. It has accelerator properties intermediate between those of MBT and MBTS, being less scorchy than MBTS and also intermediate in state of cure. The vulcanisate properties are closely similar to those of MBT. ZMBT is specially recommended for latex compounds with ZDC to give high modulus rubbers. A similar combination produces latex foams with a high compression modulus. Typical dosage varies from 0.5 - 1.5 phr.
Storage and Handling
Stable indefinitely under normal conditions of storage. No special handling precautions are necessary. Normal precautions to avoid contact with skin and eyes should be followed. For eyes, flush with plenty of water and seek medical advice.
