This is the latest ASTM Flexural Strength Test on Ultra Bond's windshield repair resins. Below is a chart that illustrates how our resins are indeed Stronger Than a New Windshield and in our thicker viscosity resin, beyond the strength of a new windshield.
The purpose of this project is to determine the strength of the laminated glass by performing impact and penetration tests following the ANSI/SAE Z26.1-1990 and flexural strength test in accordance with ASTM C-158-84.
ANSI/SAE Z26.1-1990, "America National Standard For Safety Glazing Materials For Glazing Motor Vehicles and Motor Vehicle Equipment Operating on Land Highways-Safety Code".
ASTM C158-84, "Standard Methods of Flexural Testing of Glass Determination of Modulus of Rupture)".
