Product Description
LOCTITE® AA 352™ is a one-component, UV-curable modified acrylic adhesive designed for high-speed bonding, coating and sealing applications. The product rapidly cures when exposed to ultraviolet light and can also be cured using heat or activator systems when required. Once cured, it offers excellent resistance to vibration, impact, humidity and environmental aging. LOCTITE AA 352 is commonly used for bonding glass and metal components, electrical devices, appliance parts and decorative assemblies where optical clarity, fast cure speed and durable performance are critical.
