In development EPOMIN™ P-3000 Polyethyleneimine (PEI)

  • Main Applications

    Laminate anchor coating agents for paper, cloth, OPP and PET film, Heavy metal chelating agents, Metal plating additives, Foam retainers for fire extinguishers, Immobilized enzymes, Adhesives (for PVC sol flocculants, Epoxy resin crosslinkers), Ink adhesion enhancer, Water treatment (as coagulants)

Basic Information

High molecular weight hyper-branched polyethyleneimine (in development)

EPOMIN™ P-3000 has higher molecular weight and degree of branching than P-1050. It shows superior performance.

*The values in the table are representatives and are not guaranteed values.
*1 : Molecular weight (Mw) according to the GPC method is the relative molecular weight for measured using Pullulan as the standard.
*2 : The high polymeric region (%)
means the content rate of polymers which Mw are minimum 30,000 (the origin of the high performance of P-3000) in the whole polymer.

Viscosity

In the high concentration region, the viscosity is the same as that of P-1000 and handling properties do not easily deteriorate.
