    Uploaded by

    Karishma Prabhu
    EPOFINE® - 556 is a Bisphenol-A based liquid epoxy resin which in combination with FINEHARDTM – 22962 (Based on cycloaliphatic amine chemistry) is suitable for manufacture of industrial and structural composites using infusion technique. This laminating system has low viscosity even at room temperature combined with long pot life. This has excellent chemical resistance and mechanical properties. The high glass transition temperature of this system facilitates the production of very large components for industrial and aerospace parts.

    Product Information Sheet

    EPOFINE - 556 / FINEHARD 22962


    (INFUSION RESIN SYSTEM FOR COMPOSITE TOOLS)

    PRODUCT

    EPOFINE - 556 is a Bisphenol-A based liquid epoxy resin which in combination with
    FINEHARD 22962 (Based on cycloaliphatic amine chemistry) is suitable for manufacture
    of industrial and structural composites using infusion technique. This laminating system has
    low viscosity even at room temperature combined with long pot life. This has excellent
    chemical resistance and mechanical properties. The high glass transition temperature of this
    system facilitates the production of very large components for industrial and aerospace parts.

    APPLICATION

    EPOFINE 556 / FINEHARD 22962 system is suitable for processing by Filament


    Winding, Pultrusion, Pressure moulding, Wet lay-up and Resin Transfer Moulding (RTM,
    infusion etc). Almost all high performance industrial composite parts requiring high mechanical
    strengths at elevated temperatures can be made of this system. Typical applications are tooling
    for windmill blades, aerospace and aircraft applications.

    SPECIAL FEATURES

    The following advantages make it ideal for industrial use.

    Resin : Hardener = 100 : 20 - 23 by weight


    Tolerant mixing ratio ( 2 %).
    Low viscosity resin/hardener mix, ensures proper wetting of the glass fibre.
    Curing temperature can be varied between 80oC and 150oC.
    Excellent water resistance.
    Very Good chemical resistance and electrical insulation.
    High glass transition temperature (Tg).
    Outstanding dynamic performance.
