Thermally resistant glass article

摘要

A thermally resistant article includes a silaceous substrate and a coating layer on the substrate wherein the coating layer is formed by the cured reaction product of a maleimide compound having at least two maleimide functional groups per molecule. A method for enhancing the strength of a silaceous substrate includes applying a layer of a maleimide coating composition to the core and cross-linking the coating composition to form a strength enhancing coating layer on the core.
