PURPOSE:To provide a primer which has excellent adhesion to ceramics, can be well bonded to epoxy adhesives and gives a bond having high reliability, consisting of a specified polyaminosilicone compd. and optionally an aminoalkoxy compd. CONSTITUTION:100pts.wt. polyaminosilicone compd. contg. Si atoms and at least two primary amino groups per molecule and having an amine equivalent of 150-3,000, such as dimethyl-polysiloxane, and optionally 0-15pts.wt. aminoalkoxy compd. such as aminomethyltriethoxysilane are homogeneously mixed with a solvent to obtain a primer. The primer is applied to the cleaned surface of a ceramic adhered and heat-treated at 50-200 deg.C for 10-60min. The adhered is then bonded to another article through an epoxy resin adhesive.
