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.
Claims19
A one-component curable adhesive consisting of:
- (A) a grafted phenoxy resin, (B) a polymaleimide compound, (C) an organic carbonate, and (D) a silane adhesion promoter, wherein the grafted phenoxy resin comprises carboxylic acid and/or ester functionality and wherein the silane adhesion promoter comprises an epoxy functional silane.
A one-component curable adhesive, wherein the adhesive consists of:
- (A) a grafted phenoxy resin, wherein the grafted phenoxy resin comprises carboxylic acid and/or ester functionality, (B) a polymaleimide compound, (C) an organic carbonate, (D) a silane adhesion promoter, wherein the silane adhesion promoter comprises an epoxy functional silane, and one or more of the group consisting of a solvent, a coloring agent, a plasticizer, a filler, and a rheology modifier.
