LOCTITE® EA E-40FL, 50 ml Standard Cartridge



LOCTITE® EA E-40FL is a toughened, medium viscosity, industrial-grade adhesive with a medium worklife. Once mixed, the 2-part epoxy cures at room temperature to form a flexible bondline with excellent resistance to shock and impact. When fully cured, it's resistant to a wide range of chemicals and solvents, and is an excellent electrical insulator. Ideal for bonding plastic, metal, glass, wood, ceramic, rubber, and masonry materials where flexibility is required, and perfect for low-stress, high-impact bonding applications of dissimilar materials. Typical applications include repairing strain gauges, sealing seams on fiberglass components, repairing printed circuit boards, bonding stainless steel inserts, and rubber hose to steel tubing.
