Laminated structure

Abstract

This invention relates to a curable perfluoropolyether adhesive composition comprising the following components (A) to (D): 100 parts by mass of (A) a linear perfluoropolyether compound having at least two alkenyl groups in one molecule and a perfluoropolyether structure comprising repeating units represented by -CaF2aO- in the main chain; (B) an organosilicone compound having at least two hydrogen atoms bonded to silicon atoms in one molecule; (C) a hydrosilylation reaction catalyst; and 0.05 to 5 parts by mass of (D) an organosilicone compound other than component (B), having in one molecule any two or more selected from hydrogen atoms bonded to silicon atoms, epoxy groups bonded to silicon atoms via carbon atoms or carbon atoms and oxygen atoms, and trialkoxysilyl groups bonded to silicon atoms via carbon atoms or carbon atoms and oxygen atoms. This provides a curable perfluoropolyether adhesive composition that can produce a rubbery or gel-like cured product that adheres tightly to a substrate. none
