LAB TESTS AND REAL WORLD PERFORMANCE:
State Farm was sued in a class action that claimed that windshield repair did not restore the windshield to pre-loss condition and therefore State Farm owed each policyholder wherein State Farm had paid for a windshield repair a new windshield. State Farm used a study of Ultra Bond to prove to a Supreme Court that windshield repair could be as strong as new glass.
A woman from Texas had a 12-inch long crack repaired by an Ultra Bond repair user in Texas. Months later she was in a rollover crash that nearly split the windshield into two. She noticed that the 12-inch crack repair was still intact and called the Ultra Bond user who then called Ultra Bond to relay the incident. Richard Campfield flew to the crash yard in Texas and took theses photographs.
In the United States new windshields must pass a series of federal tests to ensure safety functions of windshields. Two of these tests mimics an objecting impacting the outside of the windshield and another mimics a person hitting the windshield as in a head-on crash. To pass these tests the windshield cannot be penetrated. In these tests Ultra Bond long crack repairs not only passed these tests but the repair was still intact after impacts. The glass broke but not the long crack repair, just as it did in the rollover crash in Texas
This is a mechanical ASTM glass strength test that compares cracked and repaired laminated glass to that of new laminated glass. In this test Ultra Bond long crack repairs tested to be that of new laminated / windshield strength. Here again the crack repairs remained intact and the glass did not fail until it reached new glass strength. Meaning the glass broke, not the repair but the glass did not break until it was at new laminated glass strength.
This test compares the strength retention of fresh windshield repair resins compared to the resins after exposed to severe temperatures, sunlight and moisture. In these tests Ultra Bond windshield repair resins gained strength after exposure.
These are the tests required by the auto glass industry's ANSI standard called the Repair Of Laminated Auto Glass Standard (ROLAGS). One test requires long crack repairs to have the same clarity required of a new windshield. Another requires the repair to not fail or lose its bond to the PVB after thermal cycling wherein the repaired windshield glass is placed in a freezer, removed and hit with a heat gun at the same temperature of car defrosters. Another test is the mechanical strength test wherein the long crack repair is compared to the strength of new laminated / windshield glass before and after accelerated exposure of heat, sunlight and moisture. This tests both strength and strength retention as nothing gets more exposure to the elements than a windshield. Ultra Bond passed all of these tests and the long crack repair was unbreakable and was 152% of new windshield strength, meaning a windshield repaired by Ultra Bond is stronger than a new windshield.
