ITW Permatex® Anaerobic Flange Sealant
Categories:	Polymer; Adhesive; Thermoset
Material Notes:	Permatex® Anaerobic Flange Sealant is a single component, medium strength, thixotropic, anaerobic sealant that cures rapidly. The product cures when confined in the absence of air between close fitting metal flanges. It provides a tough, resilient, solvent and temperature resistant seal that flexes with flange movement caused by vibration, pressurization or thermal changes. The rate of cure will depend on the substrate used. The graph below shows the shear strength developed with time on grit blasted steel lap shears compared to different materials and tested according to ASTM D 1002. Where cure speed is unacceptably long, or large gaps are present, applying activator to the surface will improve cure speed. The graph below shows the shear strength developed with time using Surface Prep Activator on grit blasted steel lap shears and tested according to ASTM D 1002.
