Epoxy-resin systems, which are resistant to aging, moulding materials, components produced therefrom and the use thereof

Abstract

Epoxy-resin systems resistant to aging, molded materials and components generated from them, and their utilization. An epoxy-resin system especially suitable in the application of casting-resin methods comprising an epoxide-containing A component based on a glycidyl ether or glycidyl ester and a B component containing anhydride as a hardener is proposed, where a sterically hindered amine is added to the A component as a stabilizer to prevent aging of molded materials. Light-emitting components potted with it exhibit increased aging stability, especially as with respect to light yield over time. The epoxy-resin system can also be used for encapsulants and molding compositions, and can be blended with acrylates, for all applications, particularly in the exterior.
