Medium-viscosity modified acrylic ester adhesive for structural bonding of glass, metal, ceramic, and plastic substrates. It is a clear light amber one-component liquid that cures anaerobically at room temperature when used with LOCTITE SF 7649 activator. Typical use includes bonding rear-view mirrors to glass, and the product compensates for different thermal expansion between bonded parts. The technical data sheet lists 1,500 to 4,000 mPa·s viscosity at 25 °C, specific gravity of 1.1, fixture time of about 1 minute, and temperature resistance up to 120 °C.
