Polyurethane adhesives

Learn about the versatile features of industrial polyurethane adhesives.

Introduction

Polyurethane adhesives are very versatile, ranging from flexible to semi-rigid capable of meeting broader technical requirements. They are tough and reinforced able to withstand dynamic stress, fatigue giving durability of the joint.

Polyurethane adhesive characteristics

Polyurethane adhesives have a good affinity toward thermoplastic and thermoset materials.
They have filling capabilities, although they perform best in thin layers. They are characterized by negligible shrinkage during curing, not stressing thinner substrates
In transportation sector applications, they play a primary role in process economics.
