US 10,308,846 B2 · Ultra-violet-curable and moisture-curable adhesive composition

Abstract

Disclosed is an adhesive composition, comprising: (A) a silane terminated oligomer; (B) a (meth)acrylate monomer; (C) optionally a (meth)acrylate oligomer; (D) a photoinitiator; and (E) optionally an organometallic catalyst. The adhesive composition is both ultraviolet curable and moisture curable. Also disclosed is a method of applying the adhesive composition, comprising: (i) coating the adhesive onto the substrate to be bonded; (ii) laminating or stacking the substrate to be bonded to form an assembly; (iii) irradiating the assembly by ultraviolet irradiation; and (iv) placing the assembly under the room temperature. The adhesive composition is useful in display panels, touch panels and optical devices.
