    Glass Flake Coatings PDF

    Uploaded by

    Dinesh Chougule
    This document describes three types of glass flake coating systems - Koroglass, Chemglass, and Superglass. Koroglass and Chemglass systems embed glass flakes in epoxy or vinyl ester resin matrices respectively to provide corrosion protection. Superglass uses a polyester resin matrix. All three systems create tortuous paths through the coated substrates to improve corrosion resistance by increasing the distance ions must travel. Key properties include thickness of 500-1000 microns, hardness of 80-85 shore D, and chemical resistance passing ASTM D 6943 standards.

    GLASS FLAKE COATING

    The principle of Glass Flake coating system lies in


    providing laminar glass fillers with tortuous path
    through the resin binder so that the corrosive ions
    traveling through the binder have to travel a much
    longer distance. The distance traveled will depend
    upon the thickness of the flakes and the number of
    layers of glass flakes in a given coating.
    1) KOROGLASS

    Koroglass series is a glass flake reinforced system in which


    laminar glass fillers are embedded in solvent free matrix of
    Epoxy resin. This high performance epoxy coating system are
    recommended for enhanced protection to metal and concrete
    against erosion, corrosion and attack of chemicals. Its extremely
    low permeability with relatively high abrasion and chemical
    resistance helps to protect various industrial equipment like
    pumps, pipes tanks vessels, structures etc.

    Koroglass 200
    Koroglass 1000
    Koroglass FG
    Koroguard GF

    Applications

    Pump castings / impeller


    Cooling tower header
    Tanks & Vessels
    Internal & External surface of pipelines
    Condenser Tube plates & Water boxes
    Offshore platforms
    Penstocks

    Typical Properties

    Thickness for 2 coats 500-1000 microns


    Coverage for single coat 1-1.5 m2 /kg

    Working time for 100 gms at R.T 40-45 minutes
    Hardness shore D 85
    Chemical Resistance Passes ASTM D 6943
    2) CHEMGLASS

    Chmeglass series is a matrix of Glass flakes and vinyl ester co-


    polymer 100% solventless coating systems which offers
    excellent chemical and corrosion resistance properties. This
    three component high build system with heavy duty
    impermeable chemical resistant barrier is suitable for metal and
    concrete surface protection . The cured film is having excellent
    corrosion resistance, highly impermeable to protect the
    substrate from concentrated Acid/Alkali attacks in immersed
    conditions.

    Range
    Chemglass 150
    Chemglass 1000
    Chemglass FG
    Chemguard GF

    3) SUPERGLASS

    SUPERGLASS series is high build coating system in which laminar glass fillers are embedded in solvent
    free matrix of polyester resin offering an excellent resistance against atmospheric moisture penetration.
    Its extremely low permeability, high abrasion resistance and chemical resistance properties protect
    various industrial equipments like pump casings, impellers, pipe bends, stirrers and diffuser drums in
    severe conditions.
