1. Product overview

LOCTITE® UK U-10FL is a two-component, low-viscosity urethane adhesive that cures at room temperature to form an ultra-clear and highly flexible bond line. It offers exceptional peel strength, non-yellowing transparency, and reliable dielectric performance. With a Shore D hardness of 45 and elongation of 170%, it combines clarity with toughness, making it suitable for demanding industrial use.


2. Applications

It is ideal for bonding polycarbonate, glass, metals, and various plastics. Typical uses include assemblies requiring a clear, flexible, and durable adhesive where resistance to impact, solvents, and environmental stress is critical. Its transparency makes it particularly suited for applications demanding non-yellowing aesthetics.
