ABSTRACT:
Casting resin compositions for sealing opto-electronic components on the basis of quick-setting casting resin compounds, consisting of at least one epoxy compound with a cycloaliphatic base with at least two oxiran rings in the molecule, at least one carbonic acid anhydride, a zinc octoate, a low-molecular polyol and/or a low-molecular acid ester and, optionally, an organic phosphorus compound and customary brighteners and light-scattering material in powder form and pigments. Especially suitable is a zinc octoate with a zinc content of 21 to 22% by weight. The compounds are used for covering and coating light-emitting diodes, photo transistors, photo diodes and light-emitting diode displays and as light guides for opto-electronic couplers.
