Ultraviolet + anaerobic dual-curing adhesive
GM366 is a single-component, UV/anaerobic dual-curing acrylic adhesive specifically designed for bonding, securing, and sealing electronic components and parts. It features excellent adhesion, toughness, high impact resistance, and superior weather resistance. When used with 355 primer, it accelerates curing. Particularly recommended for buzzer plates and magnetic steel components.
