Structural urethane adhesive

Urethanes 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. LORD urethane bonding 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. 

Substrates for Urethane Bonding Adhesives

What substrates can be bonded using urethane adhesives?

  • Composites 
  • Plastics
  • Coated Metals
  • Foams
  • Textiles
  • Reinforced Thermoplastics
  • Glass
  • Rubber
  • Ceramic/Stone
  • Wood

Benefits of Using Urethane Adhesives

Why should you use urethane adhesives over other options?

  • Multiple work times and cure speeds to meet application requirements 
  • High elongation
  • Bonds to dissimilar materials
  • No odor, environmentally recommended 
  • Specialty versions to meet application requirements
  • Resist sunlight (non-yellowing)
  • Optically clear, translucent, bright white color options
  • Formulas for precise, small beads and large beads
  • Excellent adhesion on numerous composites without pre-abrasion (ex: SMC)
  • Temperature resistance within their category
