Electrical Resistivity of DC93-500 Silicone Adhesive

Abstract

Dow Corning 93-500 clear silicone adhesive is used to attach protective cover glass material to solar cells. If the resistance of the DC93-500 becomes too great as temperatures approach -150 degrees C, then there is the potential for arc discharge, which could damage spacecraft electronics. Therefore, the question of electrical resistance as a function of temperature is important to the design process. In this report, measurements of resistivity are reported as a function of temperature. A change of slope in the resistivity versus log(temperature) graph at approximately -50 degrees C is reported. This phenomenon is linked to the crystalline phase transition.
