摘要
A chemically-hardening two-component material based on polyurethane is provided, having a first component being a prepolymer with isocyanate end groups and a second component being a product which has been obtained from that prepolymer with isocyanate end groups by reacting it with a reactive compound which has at least two active groups, containing active hydrogen and which do not react identically with isocyanate. The prepolymer is a reaction product of an aliphatic or aromatic di-isocyanate with a polyol. Such a material can be produced by reacting a prepolymer which contains isocyanate end groups, with a second component, which, in turn, has resulted from a prepolymer with isocyanate end groups by reacting with a reactive compound which has at least two molecule groups, containing hydrogen and reacting differently with isocyanate. The material is especially suitable as a self-hardening gluing, coating, sealing and molding material.
