Polyisocyanates based on polyhydroxy polyethers and tolylene diisocyanate containing ether and urethane groups and having an isocyanate group content of from 11.8 to 14.4% by weight, an average isocyanate functionality of from 3.1 to 4.0 and a free tolylene diisocyanate content of less than 0.1% by weight are produced by reacting a polyhydroxy polyether having a molecular weight in the range of from about 350 to about 500 with excess quantities of tolylene diisocyanate and subsequently distilling the mixture to remove unreacted excess of the starting diisocyanate. These polyisocyanates are particularly useful in the production of polyurethane lacquers.

A process is disclosed for the production of metal sheets enamelled with two layers, wherein the sheet is coated, before shaping, with a polymer suspension. The sheet is then dried and shaped, and optionally is coated with an enamel frit. The sheet is then fired at a temperature of 560 to 850 degrees C. The binder in the polymer suspension is preferably a material which burns completely at melting and stoving temperature.

The present invention is directed to polyhydroxyl compounds containing both ether and ester groups, having an average hydroxyl functionality of 2 to 6 and an average hydroxyl number of about 100 to 600, based on the esterification product of (i) polyether polyols having an average hydroxyl functionality of 3 to 8 and an average hydroxyl number of about 200 to 1000 with (ii) about 5 to 70 equivalent %, based on the hydroxyl group of component (i) and the carboxyl group of component (ii), of organic monocarboxylic acids. The present invention is also directed to the use of the polyhydroxyl compounds as synthesis components in the production of polyurethane plastics materials by the isocyanate-polyaddition process, particularly their use as the polyol component in two-component polyurethane coating agents and/or polyurethane casting systems which are solvent-free or have a low solvent content.
