Abstract
A one-part adhesive including a grafted phenoxy resin, a polymaleimide compound, an organic carbonate, and an optional silane adhesion promoter is described. More particularly, the grafted phenoxy resin includes carboxylic acid and acrylate ester functionality. Methods of using adhesives to bond a thermoplastic urethane to a rigid substrate, e.g., in an injection or compression molding process, are also described.
Claims14
A method of bonding two dissimilar materials in an injection or compression molding process comprising:
- selecting a rigid substrate,
- selecting a liquid introduced thermoplastic urethane (TPU), and
- providing an adhesive comprising a grafted phenoxy resin and a silane adhesion promoter.
Dependencies are inferred from the claim text.
