PUR Hot Melt Adhesive

PUR (Polyurethane Reactive) Hot Melt Adhesive is a one-component adhesive that combines the benefits of hot melt and reactive chemistries. It’s applied in its molten state and quickly solidifies upon cooling, forming a durable bond that strengthens as it reacts with moisture in the air. This results in a flexible and strong adhesive with superior performance in demanding environments.

Features

Reactive Chemistry: After initial bonding, the adhesive cures with moisture, increasing bond strength over time.
Flexible Bonding: Once cured, it remains flexible, making it ideal for applications where the materials may experience movement or flexing.
High Temperature Resistance: It can withstand extreme hot and cold temperatures without losing its adhesion properties.
Excellent Durability: Resistant to water, chemicals, and UV exposure, providing long-lasting reliability in harsh conditions.
Quick Setting: It forms an initial bond rapidly, allowing faster production times and efficiency gains in your processes.

Advantages of PUR Hot Melt Adhesive

Strong, Long-Lasting Bonds: Our PUR adhesive forms incredibly tough bonds that strengthen over time, outperforming traditional hot melt adhesives.
Improved Production Efficiency: With a quick set time, your assembly lines will see faster throughput, reducing downtime and increasing productivity.
Versatility Across Materials: PUR Hot Melt Adhesive works exceptionally well on a variety of substrates like wood, plastics, metals, textiles, and even difficult surfaces such as glass or composite materials.
Resistance to Harsh Conditions: Once cured, it’s resistant to moisture, heat, chemicals, and environmental exposure, ensuring your product performs reliably in any condition.
Reduced Maintenance Costs: With its durable bonding and excellent resistance properties, you’ll experience fewer product failures, meaning less rework and maintenance.
