Abstract:
1. A reactive composition, comprising A) 10 to 99.8% by weight of a compound or mixture of compounds each comprising at least two reactive isocyanate groups in unblocked form; B) 0.1 to 3% by weight of at least one of a quaternary ammonium salt and a quaternary phosphonium salt comprising counterion, an anion selected from the group consisting of hydroxide, a halide, an anion of an organic acid, and an anion of an inorganic acid; and C) 0.1 to 5% by weight of a compound comprising an epoxy group wherein the compound comprising at least two reactive isocyanate groups is selected from the group consisting of: a) an aromatic, aliphatic or cycloaliphatic diisocyanate in pure form; b) an aromatic, aliphatic or cycloaliphatic polyisocyanate in pure form; c) an aromatic, aliphatic or cycloaliphatic diisocyanate in a form of a derivative selected from the group consisting of an isocyanurate, an allophanate, a urea, a biuret and a carbodiimide; d) an aromatic, aliphatic or cycloaliphatic polyisocyanate in a form of a derivative selected from the group consisting of an isocyanurate, an allophanate, a urea, a biuret and a carbodiimide; and a prepolymer obtained by reaction of any of a) to d) with a compound having at least two isocyanate reactive hydroxyl groups, amine groups or combination thereof, wherein the reactive composition does not include an external blocking agent, and wherein the reactive composition is curable at a temperature of from 60° C. to less than 120° C.
