Polyvinyl auxiliary for splits.
CORETAN V3 has been especially studied to achieve splits with sealed hair, and with a natural, slippery touch.
It is recommended for use when spongy splits with very open fibres have to be washed.
If ironed after drying and before the next processing stages, skins treated with CORETAN V3 will have a very resistant top film that allows easy adhesion of the finishing.
The amounts for use vary from 2 % to 4 % depending on how fibrous the structure of the skin is which requires processing.
