Notes
on Uses
Accicure MBTS is a fast curing accelerator giving vulcanisates with ultimate
properties closely similar to those of Accicure MBT. The most noticable
difference is the much greater scorch resistance of Accicure MBTS. Like
Accicure MBT, Accicure MBTS gives extremely good ageing properties; it
is practically non-staining and similarly needs the addition of stearic
acid to function at its maximum efficiency. In combination with guanidines,
thiurams and dithiocarbamates, it gives rapid curing but safe mixtures,
In Neoprene, it serves as an antiscorch agent.
Storage
and Handling
Stable indefinitely under normal storage conditions.
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.
