ACTIVITY |
|
The RUBATOR ZMBT is
slightly less active at processing temperatures than the Rubator MBT
in dry rubber compounds. It has greater processing safety and gives
fast cures above 125
°C. |
|
The RUBBATOR ZMBT gives
good aging properties and is non-staining. |
|
The RUBATOR ZBMT is
specially useful in latex foam mixes permitting the use of a lower
zinc oxide of particular utility in lightly coloured goods. |
|
USES |
|
It is used in such goods
as bathing-caps and where good colour is required. |
|
It is largely employed
in latex compounds. |
|
PACKING |
|
The RUBATOR ZMBT
is contained in 20 kg. net weight paper bags. |
