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.
