LOCTITE® AA 326 Structural Adhesive

Known as LOCTITE 326

Features and Benefits

This 2-step, no mix, medium-viscosity acrylic adhesive has a fast cure and high shear strength. It is thixotropic for ease of handling, and ideal for magnet bonding.
LOCTITE® AA 326 is a general-purpose, 2-step, medium-viscosity acrylic adhesive for fast cure and high shear strength. It has good adhesion to different types of ferrites, a fixture time of less than 3 minutes, a high shear strength of 15 N/mm², and can be used in temperatures up to 120°C (248°F). It requires LOCTITE® SF 7649 to activate and, among other applications, is perfect for magnet bonding electric motors used in elevator production.
