Resinlab® EP950G Gray Aluminum Filled Rubber Modified Epoxy
Categories:	Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive
Material Notes:	EP950G Gray is an aluminum filled one part rubber modified epoxy designed for bonding metal and other structural material subject to stress at elevated temperature. It is a medium paste-like viscosity which gives very little sag upon cure at elevated temperature. Being a 100% solids, single component product a variety of simple, low cost dispensing methods are available for application of this product. This product will cure at temperatures as low as 113°C (235°F) without sacrificing shelf life or need for unusual shipping or storage considerations.
