Henkel LOCTITE-AA-3081 (1LTR-BOTTLE)

Additional Product Information

Overview

This adhesive is a one-component, UV-curable acrylic designed for precision bonding of cannulae, syringes, and lancets. Widely used in medical device assembly, it delivers fast, reliable adhesion to glass, metal, and selected thermoplastics. Production teams rely on this product for its rapid curing, low viscosity for wicking, and UV-fluorescent properties that simplify quality inspection, ensuring consistent performance in high-speed manufacturing environments.
