Abstract

There is disclosed a thermosetting organic-inorganic hybrid transparent material which is characterized by including a main material that has a siloxane skeleton modified with an organic substituent, and a curing agent. The main material and the curing agent are mixed, and the mixture is coated on an adherend and cured by heating. With these steps, a transparent bonding/sealing is achieved.

Claims
