Storable polyol mixtures containing mold release agents

Abstract

Polyol mixtures containing a mixture of internal mold release agents which are storage stable are made up of (a) from about 55 to about 95% by weight of a polyol mixture of (1) 30-70% by weight of at least one polyol with an OH value of more than 700 and (2) from about 30 to about 70% by weight of at least one polyol with an OH value of 700 or less than 700 and (b) from about 5 to about 45% by weight of a mixture of internal mold release agents made up of (1) from about 60 to about 95% by weight of at least one salt-like release agent and (2) from about 5 to about 40% by weight of at least one non-salt-like release agent containing an amide NH function or a urethane NH function. Known auxiliaries and additives may optionally be included. These polyol mixtures are useful in the production of rigid, semirigid and flexible polyurethane materials, particularly molded polyurethanes.
