Abstract: A method of using UV cationic epoxy to repair cracks and breaks windshields in order to eliminate oxygen inhibition and shrinkage. The method includes embodiments that employ pretreatment or priming of the of a crack or break in order to negate the moisture and PVB retardation of the UV cationic epoxy polymerization and mixing the UV cationic epoxy and a UV radical resin to create a hybrid or; adding other ingredients to the UV cationic epoxy to negate the moisture and PVB retardation; and use of the UV cationic epoxy as a cap over repair resin/epoxy and as a pit filler. Other combinations of materials and procedures are disclosed.

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 means and method for protecting a windshield from damage and therefore the development of cracks due to stone or other impact on windshields around the peripheral area. An impact resistant barrier is placed around the periphery of the windshield. The barrier is preferably a clear polymeric film, but could be opaque, rubber, plastic or metal. The barrier is placed on the glass surface and in contact adjacent to the windshield molding. The width of the barrier is selected to eliminate the higher incidence of damage to the peripheral area. The barrier can be combined with a sunlight blocking ingredient to reduce degeneration of urethane which is used in mounting the windshield to the vehicle. A kit can be assembled with the elements needed to place the barrier on a windshield. The barrier can be applied in fluid form which achieves a film. The barrier can extend not only over the front surface, but also over the edge surface and the back surface.

Abstract: A method of repairing a crack in a windshield where the crack has an open portion in which the repair resin selected for use is at minimum specified at 200 c.p.s.; and in another embodiment has a maximum of 1,000 c.p.s. and in another embodiment has a viscosity of over 1,000 c.p.s.

Abstract: A method of repairing windshields which are below room temperature, in the range from about 65.degree. F. to about 40.degree. F. repaired by using a resin whose viscosity ranges from a high end of a range of about 700 c.p.s. to about 400 c.p.s. to a low end of a range of about 150 c.p.s. Also, when the windshield is below about 40.degree. F., the method uses a first low viscosity resin of 10-100 c.p.s. and a second resin from about 150 c.p.s. to about 700 c.p.s. Also, when the crack is a floater, the resin is in the range from about 100 c.p.s. to about 90 c.p.s. and is heated prior to or during injection into the crack.

In an alternative method where the crack has an unsurfaced, or tight portion, two injectors are used to fill that portion with a lower viscosity resin, one placed at the end of the crack and the other near the transition from the unsurfaced to the surfaced portion.

Abstract: A kit (150) of parts from which tools may be assembled for the repair of glass cracks by insertion of resin having an index of refraction substantially that of the glass. The tools are a repair bridge (160) and a repair bar (180) which may be placed on an automobile windshield and used to inject resin into a glass crack and a crack spreader (170) which may be placed on the inside of a windshield and used to spread the crack to facilitate entry of the resin. Methods of use of the tools are disclosed.
