Today’s urethane product formulators need to meet a wide range of consumer and regulatory requirements. As premium chemistries, reactive adhesives and sealants must be compliant, have good safety and sustainability profiles, and perform exceptionally. They must provide good adhesion and bonding, even on challenging substrates. They must be flexible, but also tough, minimizing brittleness, cracking, discoloration, and breakdown of the adhesive during its expected life span. Lastly, they must be easy to use, offering long open times and short cure times.
Urethane adhesives and sealants are valued for delivering excellent toughness, abrasion resistance, flexibility, cold temperature properties, and adhesion to a wide variety of substrate types. They have superior mechanical properties relative to other high-performance adhesive and sealant chemistries, including lower modulus, better tensile elongation, and high shear and peel strength. These attributes make urethane systems valuable in applications such as construction, packaging, and transportation.
