Main purpose:

1、 Dimer acid with an amine in an amount of different additives can generate a variety of different molecular weights participating polyamide, widely used in the manufacture of plastic embossing printing inks.

2、 Dimer acid polyamide polyamine reacts with active amine, widely used in manufacturing two-component epoxy paint, curing agents and epoxy adhesive, cured with good mechanical and electrochemical properties. In addition, also for the manufacture of a variety of low-temperature, low-pressure specialty lubricants, metal processing oil.

3、 Dimer acid used in the manufacture of hot melt adhesive, and is widely used in the manufacture of electronic and electrical products and thermoplastic automotive interiors, shoes and so on.

4、High-grade polyamide resin ; Hot Melt Adhesive  ; Lubricating oil ; Polyester resin

    Rust inhibition of oil field ; Epoxy resin curing agent.
