High-Strength Epoxy Resin

IMSEAL-800™, a high-strength epoxy resin, seals gross (visible) porosity in castings and other metal parts. It completely and permanently fills blowholes, cracks and other such defects where welding or brazing would be impractical. The clear, multi-purpose sealant is drawn deep beneath the surface, penetrating and filling the void and creating a pressure-tight seal. IMSEAL-800’s unique chemistry penetrates well below the surface of castings, filling all connected passageways and producing a superior leak-proof seal. IMSEAL-800 is also ideal for repairing common machining errors such as misplaced holes, damaged threads, tool chatter and surface nicks. Once cured, IMSEAL-800 has a tensile strength of more than 9,000 psi, a compressive strength of 35,000 psi, a compressive yield of 16,500 psi and a Rockwell hardness of 97.
