CASEIN COATINGS FOR LEATHER INSOLUBILIZED WITH ALKOXY ALKYL UREAS

摘要

CASEIN COATINGS FOR LEATHER INSOLUBILIZED WITH ALKOXY ALKYL UREAS A process is disclosed for insolubilizing casein coatings for leather utilizing alkoxy alkyl ureas. The coatings are cured in the presence of an acid catalyst. The casein coatings of the invention avoid the disadvantageous use of aldehydes such as formaldehyde and glutaraldehyde to cure the casein and reduce its water sensitivity and unexpectedly show improved wet abrasion resistance.
