<p>A compsn. rapidly cured to a tack - free state at room temp. by a tert. amine comprises (A) a polyisocyanate contg. 2 - 5 NCO gps. a polyisocyanurate, or a prepolymer thereof, (B) a phenolic addn. prod. of a phenol contg. 15C atoms and an unsatd. cpd. selected from (1) a 12 - 22C unsatd. aliphatic acid; (2) natural oils which are glycerol esters of the acids in (1); (3) synthetic esters of the acids in (1) with 1 - 22C mono- or poly - hydric alcohols; (4) butadiene homopolymers, (5) copolymers of butadiene and its homologues with vinyl monomers; or (6) synthetic esters of 1 - 22 C unsatd. aliphatic alcohols with 1 - 36 C mono- or poly - basic acids; and (C) the tert amine catalyst, e.g. triethylamine.</p> |
