Waterborne Polyurethane – The Super Glue

Almost all of us know about polyurethane that it acts as glue. Being a thermoplastic substance, it contains copies of organic chain units that are linked to urethane links. The chemical reaction of polyurethane polymer results in the creation of this adhesive, which is superbly strong and resistant to all major kinds of deterioration. Its exceptional bonding properties make it the most sought after material for a wide range of industrial and construction purposes. Though there are different types of adhesives available in the market but Waterborne Polyurethane has its own space in the market. 



The very first property is that it is completely water-resistant. It has excellent resistance to harsh alkaline and acidic chemicals and this adhesive does not dissolve or dismantle when in contact with these chemicals. It has extremely low viscosity. Moreover, the flexibility of this adhesive allows it to absorb shock and vibrations. Therefore, these properties make it most perfect for constructing buildings and furniture.

Experts suggest that due to its high adhesive properties, it becomes difficult to remove it as it creates a permanent bond with the other surface. However, acetone, a chemical solvent is found to be able removing this adhesive. In numerous application, it has been found that this adhesive takes a bit longer to firmly stick surfaces together.
