DYTEK® A amine (2-methylpentamine-1,5-diamine) is a methyl branched diamine with differential reactivity of each amine group that allows for crystallinity disruption in various applications such as high temperature nylon and polyamides, polyurethane chain extenders, and epoxy hardeners. It is also used in applications such as water treatment, corrosion inhibition, and metalworking fluids where amine functionality and pH control are important. DYTEK®A has 93% recycle content.
