Dytek® DCH-99

DYTEK® DCH-99 (1,2-diamainecyclohexane) is a cyclic aliphatic diamine made of 100% reclaimed material that is primarily used in epoxy coatings and composites. It provides chemical resistance over a broad range of chemicals, which makes it a superior choice for industrial and marine coatings. Other applications include mining, oil & gas, and pharmaceutical intermediates.
