LOCTITE AA 3921 is suitable for a wide variety of applications that require fast cure, flexibility, high adhesion and autoclave resistance. LOCTITE AA 3921 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 3921 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. ISO-10993 LOCTITE AA 3921 has been tested to Henkel’s test protocols based on ISO 10993 biocompatibility standards, as a means to assist in the selection of products for use in the medical device industry.
LOCTITE AA 3921 is a light-cured, acrylic-based adhesive formulated to provide flexible bonds when joining stress-sensitive plastics.
