Polyurethane (PUR) Hot Melts
Reactive Strength for Demanding Materials
Polyurethane (PUR) hot melt adhesives are high-performance, reactive adhesives designed to bond difficult substrates where traditional hot melts fall short. Once applied, a chemical reaction (polymerization) takes place as the adhesive reacts with ambient moisture, forming an exceptionally strong and durable bond.
PUR adhesives offer long open times, fast handling strength, and excellent resistance to heat, moisture, and chemicals—making them ideal for demanding environments. They also require less adhesive per application, improving efficiency and reducing waste.
Key Features
Reactive Bonding
Cures through moisture-initiated polymerization to form permanent, structural-strength bonds.
High Resistance
Exceptional durability against heat, chemicals, and moisture over time.
Clean Runnability
Formulated for smooth, clog-free operation with low maintenance requirements.
Wide Temperature Range
Performs reliably in both hot and cold environments with excellent service flexibility.
Efficient Usage
Increased mileage with lower coat weights reduces adhesive consumption and cost per unit.
Versatile Adhesion
Engineered for materials like plastics, laminates, metals, coated boards, and more.
Common Applications
-
Delivers superior hold on laminates, veneers, MDF, particleboard, and solid wood.
-
Used for bonding fabrics, foam, and flexible substrates in mattress and automotive interiors.
-
Forms strong, flexible spines with high page pull strength and excellent lay-flat performance.
-
Used in air filters, HVAC units, and white goods where resistance to vibration and temperature is critical.
-
Provides heat- and water-resistant bonds for woodworking and architectural finishing.
-
Used in industrial filters where strong bonding to pleated materials and metal end caps is essential for durability and performance.
Formulation Options
-
Ideal for general-purpose bonding needs where strength and durability are essential.
-
Offers smoother flow and better substrate wet-out for automated or precision application systems.
-
Designed for quick handling strength in high-speed production lines or cold press processes.
