Direct-glazing adhesives are used to bond glass or other windshield material to a motor vehicle’s body. These adhesives are used by both the original equipment manufacturer (OEM) for auto glass assembly, and by the aftermarket repair shops for auto glass replacement. Polyurethane glazing adhesives have been the industry standard for direct-glazing applications for over 30 years. Recently, growing challenges have caused industry professionals to seek alternatives that will not only overcome the current obstacles, but also continue to evolve with ever-changing technology. The once niche technology of silyl modified polymers, or SMPs have met and exceeded expectations for overcoming these obstacles.
