  • Patent number: 4994540
    Abstract: A two component urethane structural adhesive formulation was developed containing a multi-functional aromatic amine terminated polyether as part of the curative component. The adhesive of the present invention is prepared by mixing and reacting the following low viscosity components:Component A, a curative comprising a polyol and an aromatic amine terminated polyether containing two or more primary amine groups and having a molecular weight of from 250 to about 10,000 and Component B, comprising a polyisocyanate. The adhesive of the invention is characterized by its improved sag resistance, its heavy body which is obtained without resort to included fillers or to prepolymerization of the components and by the relatively low viscosity (under about 15,000 cps) of its components which permits easy bulk handling.
