There is a need from the market to improve the reliability of the GL products by increasing the adhesive strength of the interface between resin used for repair and glass surface because of peeling off during the use.}

2 As a result of our research and development for making our customers satisfy, new resin system RESIGLASS which has better adhesive strength between resin and glass surface and corrosion resistance than the repairing resin now being used has been found. To put RESIGLASS into the market in 2007, the final field tests and the improvement have been performed. Key Words|.
