Urethane Adhesives

Two-part urethane structural adhesives are different from one-part moisture-curing urethane sealants. Urethane structural adhesives are two-part formulations that react when mixed and do not require moisture to cure. They are relatively flexible when cured and therefore tend to have excellent impact and vibration resistance. Urethane structural adhesives bond well to most plastics, wood, concrete, rubber and carbon fibre, but they tend to have reduced resistance to solvents and high temperatures. 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 joining dissimilar metals and materials.
