Independent Lab Testing to meet the 2014 ROLAGS resin requirements showed that the mechanical strength of windshield glass is at least 52% stronger than new windshield glass after being cracked and repaired with Ultra Bond Windshield Crack Repair Resins. That means that after repair auto glass can be at least 152% of new undamaged auto glass strength when cracked and repaired with Ultra Bond Long Crack Windshield Repair Resins.
Per the American National Standard Institute approved Repair of Laminated Auto Glass Standard (ROLAGS) the test samples are cracked from edge to edge and then repaired.Half of the repaired samples are then tested to and compared to new undamaged samples with the other half of the repaired samples going into a QUV for accelerated weathering. The ROLAGS requires crack resin to be at least 70% of the undamaged glass strength after exposure. Every cracked and repaired sample before and after exposure far exceeded the 70% - scoring higher than the highest scoring undamaged auto glass sample. The lowest score after exposure of the repaired samples was 152% of the undamaged glass. More than double what is required to pass the standard.
Two other other characteristics of Ultra Bond's long crack resin formula that again showed up in the mechanical strength test was that the glass is what gave way and broke, not the repaired crack. The repaired crack was still intact after the glass broke. The resins also gained strength after exposure.
Lab Tests since 1993 of Ultra Bond Long Crack Repair Resins have consistently resulted in meeting and exceeding new auto glass strength.
After a real-world rollover crash in 2003, a 12-inch crack repaired with The Ultra Bond Crack Repair System was still intact. The consumer had previously had the 12-inch crack repaired by Pace Glass, owned by Jeff Redell, current President of National Windshield Repair Association (NWRA). The crack was repaired with Ultra Bond Crack Resin. When the consumer was in the rollover, the windshield was nearly split into two pieces and yet the 12-inch crack repair was still intact. The consumer, whose vehicle still had the factory seal, sustained no injuries and walked away from the crash. Photographs of the crashed vehicle, windshield and the repaired crack can be viewed on Ultra Bond's homepage at www.ultrabond.com
Ultra Bond Crack Repair Resins again passed and have consistently passed Penetration Resistance from Federal Motor Vehicle Safety Standard 205 (FMVSS 205) before and after exposure along with the same visual tests of new windshields per the FMVSS 205 - Visibility Distortion and Luminous Transmittance. Those FMVSS tests for new windshields are the same required tests in the ROLAGS.
Ultra Bond crack repair resins also passed the required Resistance to Thermal Cycling Test which is a custom windshield repair resin test that mimics windshields being hit with the over 200+ degree air from defrosters when the repaired windshield glass is at zero degrees.
Ultra Bond is a windshield repair manufacturer founded in 1989 by Richard Campfield, located in Grand Junction, Colorado. Ultra Bond sells windshield repair resins and tools and trains windshield repair technicians for free, in-person and by way of their YouTube Channel. Ultra Bond also operates a retail repair and replacement business in Colorado and Pennsylvania. Richard Campfield has been granted twenty windshield repair patents since 1992.
