Acrylic polymer in water solution.
CORETAN RCS is a acrylic resin in water solution. It has a good filling action while it keeps a smooth and firm grain easier to buff for nubuck articles.
CORETAN RCS is compatible with all chrome salts and therefore it can be used in the retanning baths before re-chroming.
It can also be used at the end of the fatliquoring process when we want to increase the grain-firmness.
The recommended amounts for use go from 3% to 5% according to the structure of the skins and the required article.
