摘要:
An improved curable siloxane-epoxy molding composition which is a blend of a phenylpolysiloxane, an aluminum catalyst, a silica filler, and an aromatic polyepoxide resin which contains at least 38 percent by weight of a polydiglycidyl ether of a bisphenol is disclosed. The molding composition has improved thermal shock crack resistance when used to encapsulate electronic devices.
