LOCTITE^® AA 3972 is a light-cure, medium viscosity, acrylic-based adhesive designed to offer high adhesion to soft PVC and for joining metals. Fixture and tack-free time are both just 5 seconds, and cure depth is >13 mm (0.5").

LOCTITE® AA 3972™ is suitable for a wide variety of applications that require fast cure, flexibility, high adhesion and autoclave resistance. LOCTITE® AA 3972™ cures in seconds when exposed to light of the proper wavelength and intensity and achieves excellent adhesion to glass, plastics and metal. The ability of this product to fluoresce under black light facilitates inspection of bonded assemblies for adhesive presence. LOCTITE® AA 3972™ was specifically designed for bonding stainless steel cannulae into hubs, syringes and lancets for needle assemblies. The viscosity of this product makes the adhesive well suited for applications where the adhesive will be dispensed in the well after the cannulae and the hub have been assembled. Suitable for use in the assembly of disposable medical devices.
