Adhesive sealant for bonding metal parts to ceramics |
摘要 |
Disclosed is a blend capable of forming a semi-interpenetrating network when cured of (A) a solution of about 30 to about 50 wt % solids in an organic solvent of a fully imidized polyimidesiloxane and (B) about 5 to about 30 pbw per 100 pbw of the polyimidesiloxane of an epoxy resin which comprises a cycloaliphatic epoxy and an epoxy curing agent. The polyimidesiloxane is the reaction product of an aromatic dianhydride and diamine. The diamine is about 5 to about 80 mole % non-siloxane containing aromatic diamine and the remainder a siloxane diamine, where the siloxane diamine is about 40 to about 80 wt % of the weight of the polyimidesiloxane. The blend is used to bond metal parts to ceramic packages.
