ADHESIVE COMPOSITION FOR PRECISION PART, DIAL FOR TIMEPIECE USING THE SAME, AND METHOD FOR MANUFACTURING DIAL FOR TIMEPIECE

摘要

PPROBLEM TO BE SOLVED: To provide an adhesive composition for precision parts which excels in room temperature storability, low-temperature curability, flowability, and adhesive properties. PSOLUTION: The adhesive composition for precision parts comprises a main agent (A) composed of a bisphenol A type epoxy resin and/or a bisphenol F type epoxy resin, an amine curing agent (B) which is solid at normal temperatures, has a softening point of 90-120°C, and an average particle diameter of ≤6 μm, and an ultrafine particulate silica (C), and the amount of the amine curing agent (B) incorporated is 1.5-2.5 times the chemical equivalent weight of the main agent (A), and the amount of the ultrafine particulate silica incorporated is 0.5-2.0 pts.wt. based on 100 pts.wt. the main agent (A).
