LOCTITE LC230242 549 is a high-performance, red, thixotropic, anaerobic, methacrylate-based thread sealant supplied in a 50ml bottle. Designed for sealing metal threads and fittings, it cures in the absence of air between close-fitting metal surfaces, effectively preventing loosening and leakage caused by shock and vibration. This sealant is suitable for fast applications, even at low temperatures, and performs well on passive metals. It offers a fixture time of 10 minutes and full cure in 24 hours, with a temperature resistance range from -55°C to +150°C. NSF P1 approved for various applications.
