More Information
Summary:Leather treatment agents contain a mixture of (a) 2-98% by weight of an adduct with a molecular weight of 500-50,000 of an alkylene oxide onto an aliphatic or aromatic compound containing one or more hydroxyl groups and (b) 98-2% by weight of a reaction product, containing carboxyl groups or salts thereof, with a molecular weight of 170-20,000 of an aliphatic, cycloaliphatic or aromatic compound containing at least two carboxyl groups or anhydrides thereof and an aliphatic or cycloaliphatic compound containing at least two hydroxyl and/or primary or secondary amino groups and, if appropiate, ether or tertiary amino groups.
