Patent ID: 7009008

Claim:
A transparent casting resin compound for casting out optoelectronic components on the basis of an acid anhydride-curable epoxy compound, said compound comprising: a mixture of an A-component and a B-component in a weight ratio in a range of 100:100 through 100:80, said resin compound having a viscosity at 25° C. of less than 3000 mPas and having a glass transition temperature of the shaped material resulting therefrom of above 130° C. said A-component comprising a mixture of a diglycidyl ether of bisphenol-A, with the prescription that cycloaliphatic epoxy compounds are excluded, and one epoxy novolak resin as a multi-functional epoxy with a proportion of 20–50 weight % in the A-component as the only epoxy components of the A-component; and said B-component comprising a zinc salt accelerator and containing a hexahydrophthalic acid anhydride as the acid anhydride.
