Product Description
LOCTITE® 348™ is a one-component, solvent-free epoxy adhesive supplied in convenient stick form for bonding, rebuilding, repairing and sealing applications. The hand-kneadable formulation combines resin and hardener in a single package and cures at room temperature after mixing. LOCTITE 348 adheres to a wide variety of substrates including metals, ceramics, wood, concrete and many rigid plastics, providing a durable bond with good mechanical strength and chemical resistance. Its non-sag consistency makes it particularly suitable for filling cracks, repairing damaged components and performing maintenance tasks in industrial environments.
