Henkel Loctite Technomelt PUR Polyurethane Adhesives
Introduction
Henkel Loctite Technomelt PUR Polyurethane Adhesives are advanced hot melt adhesives designed for industrial applications requiring strong, durable, and versatile bonding solutions. These adhesives provide superior performance compared to traditional hot melts by forming a reactive moisture-cured bond that strengthens over time, ensuring long-term durability in demanding environments.
What Makes Technomelt PUR Adhesives Unique?
Unlike standard hot melt adhesives that rely solely on cooling for adhesion, Technomelt PUR adhesives react with moisture in the air, leading to a chemical curing process. This results in an extremely strong and resilient bond with enhanced resistance to heat, humidity, and chemicals.
Key Benefits of Technomelt PUR Adhesives
✔ High Bonding Strength – Excellent adhesion to metals, plastics, wood, and composites.
✔ Fast Setting Time – Provides immediate handling strength, improving production efficiency.
✔ Superior Durability – Moisture curing ensures long-term stability and resistance to environmental stressors.
✔ Heat & Chemical Resistance – Ideal for harsh industrial applications.
✔ Low VOC & Eco-Friendly – Reduced emissions compared to solvent-based adhesives.
