Your windshield, rear window, and many vent windows are attached to the vehicle using auto glass adhesives. These adhesives are a glue-like product that will hold the auto glass in place, and meet all Federal requirements for preserving your vehicle’s crash safety system. Failure to correctly mix or install these adhesives puts your vehicle’s integrity and your family’s safety at risk.
Glass Doctor’s certified technicians install auto glass using only AGRSS approved urethane-based adhesive products from Sika and Dow Automotive. We use a “one-part” urethane that provides a consistent, quality attachment every time. These adhesives only need a short time to dry and cure, getting you on your way in as short as an hour. (Temperature and humidity may cause some delays)
High-performance vehicles like BMW, Audi, and Mercedes-Benz require the use of a high modulus urethane. This urethane provides an even stronger bond to minimize torsional stresses and enable the windshield itself to help strengthen the car’s chassis and improve handling.
Glass Doctor of Seattle technicians follow manufacturer requirements and make sure to use this high modulus urethane when specified by your vehicle manufacturer.
In an effort to minimize garbage and reduce environmental impact, we utilize “foil packs” (or “sausages”) for our installations. This packaging minimizes the waste that traditional aluminum and cardboard tubes generate.
Advantages of Urethane
- Urethane is 3 to 50 times stronger than older adhesives
- Urethane is flexible, allowing it to flex with the vehicle body over bumps
- Urethane bonds well with smooth surfaces like glass and rougher surfaces like automotive metals and paints
- Urethane is UV, chemical and water resistant
- Urethane has a tensile strength in automotive applications of at least 500 PSI
- Urethane has a lap shear strength in automotive applications of at least 500 PSI
- Urethane is non-conductive – reducing electrical interference
