Brownells High Temp Ceramic Threadlocker is a specialized adhesive formulated to secure threaded fasteners exposed to extreme temperatures, accommodating a range from -60°F to 2000°F (-51°C to 1000°C). The ceramic formulation provides exceptional thermal stability, maintaining bond integrity under extreme heat conditions. This 2oz bottle is ideal for gunsmithing applications requiring reliable fastener security in high-heat environments.
The threadlocker cures through the evaporation of water, with exposure to temperatures over 230°F (110°C) accelerating fixture time. Fixture time is 2-6 hours at 72°F (22°C), with full cure time of 24 hours at 72°F (22°C). It offers up to a 24-month shelf life once opened, ensuring long-term usability. The ceramic-based high-temperature compound holds under extreme heat and pressure but isn’t as difficult to break loose as red threadlocker, making it a smart choice for high-temp applications.
Parts must be clean, dry, and free from oil or grease before application. Apply the threadlocker to the threads, covering a length approximately 1.5 times the diameter of the part. Perfect for muzzle devices, suppressor mounts, and other components requiring superior thermal performance in demanding shooting environments.
