<p>A novel aqueous release agent is described which contains as release-active substances oil, fat, wax, fatty amines and/or esters of fatty acids with fatty alcohols emulsified in water as the carrier and a specific emulsifier system, which consists of a blend of neutralized cationic quaternary ammonium compounds and anionic soaps. Surprisingly the system does not flocculate desPite the opposite charge of the two emulsifier components and leads to a more flexible, elastic and pressure restistant release agent film than conventional release agents for use in processes for producing articles from polyurethane foam.</p> |
