Compositions of ВК-36 film adhesive were analyzed by using Fourier-transform infrared spectroscopy (FTIR) and X-ray photon electron spectroscopy (XPS). Main compositions of ВК-36 film adhesive are similar to those of SY-14A film adhesive except that ВК-36 film adhesive has a great amount of aluminum powder and fumed silica. Dynamic differential scanning calorimetry (DSC) experiments at multiple heating rates (

β

) were performed to obtaine the characteristic reaction temperatures (maximum cure peak temperatures

) of ВК-36 film adhesive. Based on changes of

by which the apparent activation energy (
