LOCTITE® EA 3450
Features and Benefits
This 2-part epoxy-based metal bonder develops high strength and is suitable to level surface irregularities.
LOCTITE® EA 3450 is a 2-part epoxy adhesive, which cures rapidly at room temperature after mixing. It is a metal bonding adhesive that develops high strength. The gap filling properties make this adhesive system suitable for rough and poorly fitting surfaces made from metal, ceramic, rigid plastics or wood. Applications include bonding aluminum window frames and GRP panels.
