Urethane Adhesives

LORD® Urethane-Based Structural Adhesives

LORD urethane-based structural adhesives are an excellent choice for bonding to a wide variety of thermoplastics and composites, plus difficult to bond substrates such as fabric, foam and wood. They can also be used for metal bonding applications where the metal is primed or coated. Our urethane adhesives have low odor, can deliver fast or slow cure times and have the combination of high toughness, strength, and flexibility that makes these adhesives an ideal choice for joining both lightweight and structural assemblies.

What Are Urethane Adhesives?

Urethane adhesives are formulated with much lower viscosity compared to epoxy or acrylic adhesives. Also, Urethane adhesives can be offered as either one and two component systems. Click below to learn more...
