A one-component epoxy-modified polyurethane and/or urea adhesive includes very high levels of reactive urethane group- and/or urea group-containing tougheners, an epoxy resin and epoxy hardener. These adhesives are formulated to cure at high temperatures and surprisingly provide high elongations, excellent thermal stability and good adhesive properties.

One-component epoxy-modified polyurethane and/or polyurea adhesives having high elongation and excellent thermal stability, and assembly processes using same

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.

Epoxy resin compositions for pre-gel ovens

The invention relates to resin compositions for epoxy adhesives, comprising a di-functional aromatic epoxy compound. The resin compositions and/or uncured adhesive compositions having low viscosity at low temperatures. Adhesives made therefrom have good strength and bulk properties. The invention includes methods of making and using the compositions, as well as adhesives made from the compositions.
