Permatex Surface Insensitive Thread locker BLUE is a medium strength anaerobic thread locking 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. The rate of cure will depend on the material used. Permatex Surface Insensitive Threadlocker BLUE will react faster and stronger with Active Metals. However, Inactive Metals will require the use of an activator (Surface Prep) to obtain maximum strength and cure speed at room temperature. The rate of cure will depend on the ambient temperature. Full cure is attainable in 24 hours at room temperature, 22°C (72°F), or 1 hour at 93°C (200°F). Where cure speed is unacceptably long, or large gaps are present, applying an activator (Surface Prep) to the surface will improve cure speed. A 3/8-16 steel nut and bolt assembly will fixture in about 5 minutes using an activator, while fixturing will occur in about 20 minutes without an activator. Full cure in 24 hours for both procedures. The graph below shows the breakaway strength developed with time using Permatex Surface Prep Activator. Information provided by ITW Performance Polymers. |
