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.

Examples of Applications
Promotes adhesion of extrusion laminate
Water treatment agents (Coagulants, Flocculants, Chelating agents)
Paper making agents (Fixing agents, Yield-improving agents)
Details of Functions
Adhesion
Highly adhesive with a wide range of combinations of base materials/resin.

*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.
