LOCTITE® HHD 3894 S is a one-part polyurethane hot melt adhesive supplied as a white solid. It cures by moisture and is characterized by high strength, excellent heat resistance, and good flexibility. Unlike conventional hot melts, it can be applied at relatively low temperatures, making it safer and more efficient for sensitive assemblies. The adhesive is 100% solids, requires no mixing, and is designed for structural bonding where durability under heat and stress is critical.
Structural bonding of plastics, metals, and ink-coated surfaces.
Device assembly requiring high reliability and heat resistance.
Situations demanding flexibility alongside mechanical strength.
