| Permatex® Pneumatic/Hydraulic Sealant is a single component, high viscosity anaerobic pipe sealant material. The product cures when confined in the absence of air between close fitting metal surfaces. Permatex Pneumatic/Hydraulic Sealant locks and seals high-pressure fluid power systems with tapered fittings. The rate of cure will depend on the material used. Permatex Pneumatic/Hydraulic Sealant 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. Where cure speed is unacceptably long, or large gaps are present, applying an activator (Surface Prep) to the surface will improve cure speed. The graph below shows the shear strength developed with time on 1/2” NPT fittings using Permatex Surface Prep Activator. Information provided by ITW Performance Polymers. |
