Abstract
Provided are articles, along with related methods, capable of providing an effective adhesive bond to a substrate containing polyetherketoneketone. The multilayered article includes a substrate comprising polyetherketoneketone, an adhesion promoter disposed on the substrate, the adhesion promoter comprising at least one of organotitanate, polyamide, surface-treated nanosilica, ammosilane or epoxy silane, and an adhesive bonded to the adhesion promoter. The adhesive contains at least one of an acrylic polymer, a polysulfide, a polythioether, an epoxy resin, or a silicone resin.
Claims16
A multilayered article comprising:
- a substrate comprising polyetherketoneketone;
- an adhesion promoter disposed on the substrate, the adhesion promoter comprising at least one of organotitanate, polyamide, surface-treated nanosilica, aminosilane, or epoxy silane;
- and
- an adhesive bonded to the adhesion promoter, the adhesive comprising at least one of an acrylic polymer, a polysulfide, a polythioether, an epoxy resin, or a silicone resin.
A method of enhancing bond strength of an adhesive to a polyetherketoneketone-containing substrate, the method comprising:
- disposing an adhesion promoter on the polyetherketoneketone-containing substrate, the adhesion promoter comprising at least one of organotitanate, polyamide, surface-treated nanosilica, aminosilane, or epoxy silane.
