Permatex Penetrating Grade Thread locker GREEN 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 in the absence of air and when confined between close fitting metal surfaces. Because of its low viscosity and capillary action, the product wicks between engaged threads and eliminates the need to disassemble, apply product and then reassemble. The high prevailing torque provides vibration resistance to adjustment screws. Ideal for all threaded engagements less than or equal to 1/2 inch in diameter. The product can also fill porosity in welds, castings and powder metal parts. Excellent chemical resistance and temperature range of -54°C to +149°C (-65°F to +300°F). Meets or exceeds the requirements of Military Specification Mil-S-46163A Type III, Grade R. NSF White Book registered. The rate of cure will depend on the material used. Permatex Penetrating Grade Threadlocker GREEN 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 3 minutes using an activator, while fixturing will occur in 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. |
