ITW Insulcast® 125 Epoxy Potting/Encapsulation Compound
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Insulcast® solutions are compounds designed for potting and encapsulating. INSULCAST 125 is a low viscosity, general purpose potting and casting compound. The low viscosity enables it to be used in potting densely packed modules, thereby insuring good flow and penetration around components. INSULCAST 125 contains non-abrasive fillers and is suitable for automaticdispensing equipment. Information provided by ITW Performance Polymers.
