Toray G-85FR Prepreg System - Resin Properties
Categories:	Polymer; Thermoset
Material Notes:	G-85FR is a resin system developed specifically to meet the needs of the automotive industry. A 10 minute cure time at 325°F makes it suitable for high throughput processes, and its flame retardancy and high heat tolerance make it ideal for racing applications. This system also offers easy handleability, and the capability to achieve a class “A” surface finish. Information provided by Toray Composite Materials America, Inc.
