Abstract
The invention relates to a process for adhesively bonding the surface of a humidity sensitive glass article by: PA1 (A) bringing the surface to be strengthened into contact with an aqueous solution of an acid and a silane; then PA1 (B) bringing the surface to be strengthened into contact with an alkaline aqueous solution of sodium silicate and/or potassium silicate; and PA1 (C) drying and hardening the coating applied on the surface of the glass as the result of steps (A) and (B). PA1 (D) Then adhesively bonding the glass article to another component to form a composite glass article. Application to the production of optical fiber couplers and composite lenses.
