ABSTRACT:
An organic polyisocyanate composition contains from 99 to 60 parts by weight of a liquid organic polyisocyanate and from 1 to 40 parts of a 90:10 to 10:90 mixture of a wax and a liquid ester having a molecular weight of at least 250, for example an alkyl ester of an aliphatic carboxylic acid derived from an alkyl alcohol containing from 3 to 30 carbon atoms and a saturated or unsaturated fatty acid containing from 10 to 25 carbon atoms. The composition is useful for the manufacture of sheets or moulded bodies by the hot-pressing of a lignocellulosic material and promotes release of the material from the press. The composition is preferably applied in the form of an aqueous emulsion.
