Polyurethane Adhesives


Polyurethane adhesives are used primarily in the assembly of printed-wiring boards to attach large components such as capacitors, magnetics, heat sinks, and connectors.

Key benefits of PU adhesives include flexibility, absorption of stresses, vibration damping, and thermal transfer. Being thermoplastic, polyurethanes are also easier to rework than epoxies.

Explore and learn about latest advancements and developments in polyurethane adhesives.
