 Its properties include heat resistance, medium resistance, aging resistance, heat resistance of it in order to change the temperature test under different bonding strength, the vast majority of currently used adhesive is prepared by organic polymer material, compared with metal and silicate inorganic material, easily aging deterioration the problem.
