Material Notes:
Master Bond Polymer Adhesive EP21TDCHT-LO is a two component epoxy adhesive formulated to cure at room temperature or more rapidly at elevated temperatures, with a very forgiving and convenient one to one mix ratio. Upon curing, the EP21TDCHT-LO offers high shear and peel strength which allows it to be used in a number of demanding situations including temperature cycling, as well as high vibration and mechanical shock. It will bond well to most metals, plastics, rubbers, glass and ceramics.
