Bondloc B401 Medium Viscosity Cyanoacrylate, 20g

The Bondloc B401 Medium Viscosity Cyanoacrylate is a high-performance adhesive that bonds a wide range of materials, including metals, plastics, wood, ceramics, rubber, leather, card, and glass. As a cyanoacrylate-based adhesive, it cures rapidly upon contact with surface moisture, forming a strong, durable bond within seconds—a characteristic that has earned this type of adhesive the nickname 'superglue.'

This medium viscosity formula ensures optimal flow and penetration into close-fitting joints, making it ideal for precision applications. It reacts with the naturally occurring moisture on most surfaces, initiating polymerisation, which results in a quick and robust bond. Newer gelled variants allow for curing in wider gaps, but this liquid version is best suited for tight joints and small plastic or rubber components.

Key Features

• Fast curing—bonds within seconds when exposed to surface moisture.
• Versatile bonding—works on metals, plastics, wood, ceramics, rubber, leather, and more.
