EDISON, NJ—A new "Underwater CordobondÒ"epoxy system from Ferro Corporation repairs medium to large holes, cracks and other defects in a variety of materials located in dry, moist, wet or submerged environments. Unlike conventional epoxies, the two-part workable paste is said to permeate water molecules and adhere tenaciously to the substrate, producing high strength, long lasting repairs with outstanding impact strength, tensile strength, and abrasion resistance.
The new product reportedly bonds to dry or wet steel, iron, aluminum, bronze, and other metals, as well as wood, ceramic, masonry, thermoset plastics/composites (epoxy, polyester, phenolics, etc.), and certain thermoplastics.
The diversity of materials and conditions for which Underwater Cordobond epoxy is suitable is said to broaden its application range beyond that of conventional epoxies for both emergency and scheduled repairs, most notably in the marine, wastewater, pulp/paper, chemical and other industries. Typical uses include the repair of holes and ruptures to complete breaks in hulls, pipes, pumps, ducts, tanks, valves, flanges, joints, machinery casings, and equipment carrying water, steam, gases, gasoline, oil, alcohol, and caustics.
It is relatively high in viscosity to maintain shape and cohesiveness in wet or submerged conditions in its pre-cured state, and is reportedly easy to mix and apply.
It cures at temperatures as low as 39ºF and is gray in color.
