Urethane structural adhesives are two-part formulations that react when mixed and do not require moisture to cure. … The combination of flexibility and the ability to form strong bonds to a variety of substrates makes two-component urethane structural adhesives an excellent choice for bonding dissimilar materials.
What is urethane adhesive used for?
Available in one- and two-component formulations, urethane adhesives are ideal for bonding metal, plastic and composites. Urethane adhesives resist impacts and have excellent cleavage and peel strength.
How does urethane adhesive work?
Polyurethane adhesives are formed by the reaction of various types of isocyanates with polyols. The polar urethane group enables adhesion to various surfaces. Depending on the raw materials, glue lines with rubber-like elastic to brittle-hard behavior can be achieved.
