  1. URETHANE VS BUTYL WINDSHIELD ADHESIVE

  2. Urethane Windshield Adhesive Urethane is the common name for Polyurethane. It's an adhesive designed specifically for sealing and bonding windshields, side windows, quarter glass, and rear window back glass in the automotive industry. Urethane is a dark material that cures completely and is quite flexible. Urethane is now employed in high-performance car glass bonding applications in both foreign and domestic vehicles as technology advances.

  3. Benefits of Using Urethane • Urethane has the capacity to endure significant levels of deformation while maintaining adhesive strength and function. • They are abrasion-resistant and robust. • The Beta seal urethane adhesives are designed to survive prolonged exposure to the elements. • Polyurethane has a holding strength of 10,000 PSI once it has been cured. This is highly robust and will keep any windshield firmly attached to the vehicle. • Because of its flexibility, polyurethane works well as a windshield adhesive.

  4. Butyl Windshield Adhesive Butyl is actually a windshield sealant, not an adhesive. Butyl is a black, sticky material that seals holes well but is no longer used as a windshield glue. It was popular until the 1970s and costs about half as much as urethane. As a result, despite the fact that it is not as safe, many installers continue to use it. Butyl is still a good sealer and can be used to close minor holes despite this. It is resistant to stress and temperature fluctuations. Butyl does not cure or harden after installation, unlike urethane, it does not form a strong bond with the car. This leads to the windshield having an extremely weak attachment with the car, causing the glass to eject from the vehicle during frontal accidents.

  5. Urethane or Butyl- Which to Use? Which one of these to use totally depends on your requirements. So, if you have a chipped or cracked windshield that has to be replaced, it is best to seek the help of professionals. Also, do enquire if the windshield experts replace it according to manufacturer specifications and is AGRSS approved. You should also enquire about whether they utilise urethane as an adhesive and how long they recommend the automobile be left to cure before driving.
