Medium/high strength threadlocking fluid designed for fixing and sealing threaded joints. Its low viscosity and capillary action allow it to penetrate between the threads of the joint, eliminating the need to dismantle the joint before applying the product. The product cures without contact with air between closely fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The product can also fill pores in welds, castings and metal powder parts.
