Abstract
Described herein are glass articles and methods of making glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier or bonded together using a coating layer, which is preferably an organosiloxane polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The coating layer bonds the thin sheet and carrier together to prevent a permanent bond at high temperature processing while at the same time maintaining a sufficient bond to prevent delamination during high temperature processing.
