Polyurethane structural adhesive
Polyurethane structural adhesive is a high-performance adhesive that uses polyurethane prepolymer as its base material and cures through moisture or heat to form elastic polymers. After curing, it exhibits outstanding toughness and impact fatigue resistance. It can form strong bonds with a variety of substrates such as metals, composite materials, engineering plastics, wood, and concrete. At the same time, it has an adjustable elastic modulus that can range from semi-rigid to highly elastic, making it particularly suitable for joining scenarios that require vibration damping, impact resistance, and tolerance of deformation. It is one of the core adhesive types in fields such as automotive manufacturing, building assembly, and composite material joining.
