Abstract: An epoxy adhesive composition is provided that has superior wash-off resistance after pre-gelling, and may be used, for example, in manufacturing processes, for example, in the automobile industry. The composition also provides unique viscosity profile after pre-gelling to significantly reduce failure mode in subsequent processing steps. In preferred embodiments the adhesive composition comprises an epoxy type resin and a gelling agent selected from polyesterdiols and polyvinyl butyrals.
