ITW Insulcast® INSULGEL 70 CC Epoxy Potting/Encapsulation Compound
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Insulcast® solutions are compounds designed for potting and encapsulating. NSULGEL 70 CC is an epoxy compound exhibiting low shrinkage and thermal shock resistance. By making use of an inherently flexible epoxy resin and special filler technology, INSULGEL 70 CC provides reduced shrinkage and low coefficient of thermal expansion. This results in decreased stress and improved adhesion to components. Several curing agents for INSULGEL 70 CC are offered to satisfy such diverse requirements as fast cure for small components, extended pot life for uses involving large mixed quantities, and a heat cure hardener for higher temperature requirements.
