Built to Perform in Oily Environments

Unlike standard threadlockers that require spotless surfaces. Bondloc B243 thrives where others struggle.

This feature alone saves significant time during assembly or repairs, especially in challenging environments.

Secure Fastening Across a Range of Materials

Bondloc B243 works equally well on active metals like brass and copper. As well as passive substrates such as stainless steel and plated surfaces. Its medium strength formulation provides a breakaway torque greater than 25Nm on steel (tested to ISO 10964). Offering a firm hold while still allowing disassembly with standard tools when necessary.

Once cured, it maintains performance in a wide temperature range from -55°C to +180°C, making it ideal for environments with fluctuating or extreme temperatures.
