LOCTITE® AA 331

Known as Loctite 331 Structural Adhesive

Features and Benefits

This toughened, medium-viscosity, acrylic-based adhesive paste is designed for bonding metal substrates, and ideal for magnet bonding.
LOCTITE® AA 331 is a 1-part, toughened, acrylic-based structural paste with medium viscosity. Specially designed for bonding metal substrates, it’s perfect for DC motor assembly, magnet bonding, and bonding of pre-coated sheet metal. It cures in <2 minutes via activator, and you can expect high shear- and impact-strength with excellent environmental and chemical resistance. It requires activator LOCTITE® SF 7387.
