Permatex Surface Insensitive Threadlocker BLUE is a medium strength anaerobic threadlocking material which cures between engaged threads to form a unitized assembly that helps resist leakage shock and vibration. the product is a single component anaerobic liquid that cures when confined in the absence of air between close fitting metal surfaces. Ideal for all 1/4 inch to ¾ inch diameter nut and bolt assemblies achieving significant strength even in the presence of light oils. Excellent chemical resistance and a temperature resistance range of -54 C to +149 C (-65 F to +300 F). Easily removable with hand tools for servicing requirements.
