SLEPPMEDELSLOSNING FOR FORMAVSKILJNING AV POLYURETANSKUM

摘要

A process for the separation of molded polyurethane foams from the mold therefor is achieved by use of solutions of separating agents consisting of a solution of neutral magnesium salts of alpha -sulfocarboxylic acids having from 8 to 26 carbon atoms in a mixture of 30 to 70 parts by volume of water and 70 to 30 parts by volume of a solvent system, consisting of lower aliphatic alcohols having 1 to 4 carbon atoms and preferably lower aliphatic ketones having 3 to 4 carbon atoms in the ratio of at least 50 parts by volume of alcohol to at most 50 parts by volume of ketone.
