PG-FLANEC is a special flange paste-sealant that creates a reliable “forming-on-spot” ultra-thin gasket on flat flameproof joint. This sealant is applied for ensuring IP68 degree of protection of explosion-proof equipment where a small explosion-proof gap between surfaces of flat flanges is required. Black PG-FLANEC paste dries slowly and forms a soft adherent film. PG-FLANEC prevents aging of surfaces, protects against exposure to environment (including sea water and acid mine drainage) and against thermal cycles, it does not harden, shrink or crack.
