Tra-Con Tra-Bond 2123 Metal Repair Steel/Epoxy Adhesive
Categories: Polymer; Adhesive; Thermoset; Epoxy; Filled/Reinforced Thermoset

Material Notes: TRA-BOND 2123 is a versatile steel metal/epoxy adhesive formulation developed for modern industrial repair, casting and bonding applications where a steel-like or cast iron finish is required. This easy-to-use adhesive system contains no solvents and cures fairly rapidly at room temperature to a hard, low shrinkage solid, which bonds readily to steel, aluminum, and other metals, wood, concrete, glass, ceramics and many plastics. Fully cured TRA-BOND 2123 is tough and durable, resistant to water, mild acids and alkalis, salts and salt solutions, lubricating oils, petroleum solvents, gasoline, jet fuels, alcohol and many other organic and inorganic materials, While it may be attracted to a magnet, it is essentially an electrical insulator which can be readily drilled, cut, sawed and machined with regular metal working tools Typical repair applications: jigs, molds, dies, fixtures, plumbing, automotive, castings, aircraft, ships, marine, salvage.
