LOCTITE 49550 General Purpose Cyanoacrylate Adhesive

LOCTITE 495 is a versatile cyanoacrylate instant adhesive designed for a wide range of bonding applications. Its low viscosity allows for easy application, while its rapid cure time ensures efficient assembly processes. Ideal for bonding plastics, rubbers, and metals, this adhesive provides a strong and durable bond. For optimal performance, clean surfaces are recommended, and thin bond gaps are preferred. While full functional strength is achieved quickly, full chemical and solvent resistance requires 24 hours of curing.
