Polyurethane was found by a German industrial chemist Dr. Otto Bayer in 1937. This compound was introduced in the US markets in 1992 and over time, it became one of the best adhesives for construction jobs. When you use adhesive made of this compound, you need to initiate a chemical reaction to make it cure. Moisture is the element that starts this reaction.

Using polyurethane adhesive might feel a bit messy if you compare it with other types of adhesives. But when it comes to actual application, you won’t face much trouble or complications. In this short blog, we will be taking a quick look at why polyurethane is considered a good adhesive. Let’s get started.
- The amazing thing about a polyurethane adhesive is that it can bond a wide variety of materials such as polycarbonate, nylon, vulcanized rubber, ABS, primed metals, etc. If you need to bond two metals together, it is important that you keep in mind to moist the surfaces before you apply the glue.
- These adhesives are also popular for being waterproof. This feature makes polyurethane best for outdoor projects. Just don’t leave them under water for a very long time.
- Many adhesives’ effectiveness go down when they are painted on. This is not the case with polyurethane, which can be painted on once it is properly cured.
- In comparison to epoxies, polyurethane has a shorter set time. We will advise you to use clamping as well to be on safer side.
