Abstract: The novel features in the mfr. of heat-hardenable, one-component polyurethanes on the basis of (A) polyisocyanates, (B) high mol.wt. reactive H cpds. and opt. also (c) low mol.wt. chain extenders or crosslinkers, plasticisers, catalyst and/or other conventional additives, are that (i) (A) is a finely-divided polyisocyanate 0.1-25 equiv.% of whose NCO surface gps. are de-activated; and (ii) (B) is a mixt. of (B1) 5-40 wt.% (based on (B)) of an aliphatic polyether-polyamine and (B2) 95-60 wt.% polyol mixt. consisting of (a) 10-60 wt.% polyesterpolyol with a carboxylic acid ester and/or polycarboxylic acid ester structure; and (b) 90-40 wt.% polyether-polyol with mainly prim. OH functionality.
