What is polyurethane adhesive?

 One of the main reasons that Auto glass does not seal properly after installation is the use of poor quality and cheap glue.  The amount and size of glue is also an important issue that some do not pay attention to.  Black polyurethane glue is a sample of high quality adhesive used in this industry.

Due to the weight of the car windshield (laminated glass), different conditions of keeping the car in extreme heat and cold, moving the car at high speeds or different bumps, etc., all these cases indicate the need to use high-quality and strong adhesive.

Drying time of car glass adhesive

 High quality polyurethane adhesive dries in one to three hours and seals the car window.  Of course, we advise our dear customers not to go to the car wash for 48 hours after washing to install the glass so that the glass is properly sealed.

Polyurethane adhesive is very resistant to high temperatures and maintains its stability up to the maximum temperature (4 ° C).  They are very flexible when dry and are resistant to dissolution in strong acidic or alkaline chemicals. This adhesive is used in various commercial industries as well as in entertainment and handicrafts.  Some polyurethane adhesives are formulated in such a way that they can be used as a sealant or putty.
