Abstract:
A multilayer, flat molding having a visible side and a supporting layer, said visible side consisting of a polyurethane layer that has been obtained by curing a first mixture containing:a1) surface coating polyisocyanates based on 1,6-diisocyanatohexane and/or isophorone diisocyanate having a viscosity of 100 to 10,000 mPa.multidot.s and an NCO content of 5 to 30 wt. %,b1) a polyester and/or polyether having a viscosity of 200 to 5000 mPa.multidot.s and an OH group content corresponding to an OH number of 33 to 1000,c1) optionally, conventional pigments, fillers, additives and catalysts, as well asd1) optionally, solvents in amounts of at most 5 wt. %,and the supporting layer consisting of a polyurethane layer that has been obtained by curing a second mixture containinga2) semi-prepolymers based on diphenylmethane diisocyanate and a polyether polyol having an NCO content of 20 to 30 wt. %,b2) polyether polyols having an OH number of 250 to 400, andc2) 10 to 60 wt. % based on said second mixture, of reinforcing fillers and/or fibers.
