Abstract: A pre-treatment chemical mixture of hydrofluoric acid or ammonium bifluoride and isopropyl alcohol for glass adhesive applications. In one particular a pretreatment for the repair of stone breaks and long cracks in windshields. The pretreatment improves the repair by removing, through evaporation of the solvent, isopropyl alcohol, the hydrophobic coating that has been applied to the windshield when it was manufactured and simultaneously etching the sides of the stone break or long crack in a way that allows better adhesion by the adhesive repair resin while not leaving any trace of the etching after the repair is complete, thereby keeping the windshield or other glass, clear.

Abstract: A laminated glass repair tool includes an injector body having a passage for applying a vacuum to a damaged area; a side chamber connected to the passage; and a resin reservoir movable within the side chamber between a first position in which resin provided in the resin reservoir is prevented from entering the passage in the injector body and a second position in which resin is allowed to flow into the passage in the injector body. A method for repairing laminated glass includes sealing the injector body to a damaged area of laminated glass; providing the filled resin reservoir in the side chamber; applying a vacuum to the damaged area of laminated glass through the passage while maintaining the resin reservoir in the first position; and moving the resin reservoir to the second position in to allow the resin to flow into the passage in the injector body.
