Abstract (en)
[origin: WO9632431A1] The invention concerns a low-viscosity polyurethane prepolymer consisting of: a) organic polyisocyanates; b) polyols selected from the group comprising hydroxypolyester polyols, hydroxylpolyetherpolyols and their mixed polyols; c) organic natural substances with at least one hydroxyl group, a carboxyl group, an ester group or a conjugatable double bond; d) phosphoric acid ester as marker; d) viscosity stabilizers; and f) acceleration catalysts for hardening the prepolymer selected from the group comprising organic and organometallic amines.
