PUR5110 – Reactive Polyurethane Hot Melt Adhesive (PUR HMA) for Automotive & Electronics Assembly
PUR5110 is a premium one-component, 100% solid, solvent-free reactive polyurethane hot melt adhesive (PUR HMA) engineered for high-precision industrial manufacturing. Applied at elevated temperatures, it delivers exceptional immediate handling strength upon solidification, allowing fast-paced downstream processing. Through its secondary moisture-cure mechanism, the polymer chains cross-link to form a highly durable, non-remelting, and thermally stable joint. This makes PUR5110 the ultimate choice for demanding structural bonding applications where component integrity under harsh environments is critical.
Features and benefits
-
Immediate Green Strength: High initial bond strength enables instant handling and rapid downstream processing, optimizing assembly line cycle times.
-
Automated Dispensing Ready: Perfectly suited for automated heating dispensing equipment with zero stringing for clean manufacturing.
-
Cross-linked Durability: Reacts with ambient moisture to form a strong urethane network; the fully cured joint does not remelt and ensures thermal stability.
-
Multi-Substrate Adhesion: Demonstrates excellent adhesion to composites, plastics, metals, technical fabrics, and wood.
-
Eco-Friendly Formulation: Solvent-free, 100% solid composition meets strict low-VOC environmental regulations for high-tech production facilities.
