    Product Benefits

    Bonding Capabilities

    • Cilbond 10E bonds NBR compounds with high and low acrylonitrile contents with equal effectiveness and is the first choice for ACM compounds. Cilbond 10E is particularly suitable for HNBR and highly extended NBR, PVC/NBR blends and Vamac G and Vamac D, where good resistance to ingredients migrating out of the elastomer is required.
    • It bonds to all metal substrates and polar thermoplastics such as polyamides, PPO, PPS, PES, POM and thermoset plastics such as PF, MF, RF, GRP/FRP and epoxies.

    Processing Benefits

    • The extremely tough dry films of Cilbond 10E means that coated components can be subjected toconsiderable mechanical handling, without fear of chipping or peeling of the bonding agent.
    • Cilbond 10E also resists wiping on injection moulding and does not mould foul.
    • Cilbond 10E bonds effectively at low and high temperatures (between 130ᵒC and 200ᵒC) and has excellent pre-bake resistance (up to 30 minutes at 160ᵒC)

    In-service Benefits
    Components bonded with Cilbond 10E (especially when used with the Cilbond 80ET cover-coat) show :

    • Good all-round resistance to hot and cold lubricants and fluids.
    • Very good salt-spray resistance to 5% salt-water at 35ᵒC, even with 30% extension of the elastomer.
    • Good boiling water resistance, showing bond retention at 100ᵒC under a 2kg / 25mm peel width for up to 100 hours.

    Metal Surface Preparation

    • For optimum bonding with Cilbond 10E all metal surfaces MUST be contaminant free.
    • Grit-blasting with 200 – 400 sharp iron grit, or blasting with aluminum oxide grit to a gray-white finishshould yield excellent bonding surfaces with ferrous metals. After blasting, all parts should be degreased for maximum environmental resistance.
    • Cold rolled steel is normally iron grit-blasted. Stainless steel, aluminum, brass and other non-ferrous metals are normally blasted with aluminum oxide. Alternatively, proprietary phosphate treatments may be used.

    Agitation: Cilbond 10E needs to be thoroughly stirred before use with an effective agitator.

    Brushing: Application by brushing is normally undertaken without further dilution, but for coating large areas, dilution with MEK or MIBK is possible.

    Dipping: Should normally be undertaken without dilution, but MIBK or MEK is recommended if required. For tumble dipping, dilute with MEK. For many dipping applications, dilution to a viscosity of 14 - 24 seconds on a No 2 Zahn Cup, or 12 - 20 sec on a DIN 4 Cup, Ford 4 cup or a Frikmar Cup (at the bath temperature) is typical.

    Spraying: Spraying with Cilbond 10E should be conducted at a viscosity of 16-24 seconds on a Zahn 2 Cup or 13-20 seconds on a Din 4 Cup, Ford 4 Cup or Frikmar Cup at the temperature of application.
    For most conventional spray systems use a nozzle of 1.0 - 1.5 mm, a fluid pressure of 0.5 - 1.5 bar and an air pressure of 1.5 – 2.0 bar. Excessive air pressure can cause cob-webbing.

    Dilution: Irrespective of the diluent used, it is vital that the bonding agent is stirred whilst solvent is added to ensure a homogeneous mix, so that a uniform film thickness will result on application. For continuous dipping or spraying it is recommended that constant stirring is undertaken, especially if the product has been diluted. For most spraying applications, dilution with 1 part by volume of solvent to 2-3 parts of Cilbond 10E is typical. For tumble spraying, it is normal to dilute with up to 4 or more parts of solvent to 1 part of Cilbond 10E.
    Recommended diluents include: Xylene, Toluene, Ketones (such as MIBK or MEK), Glycol Ether Esters.

    Coating Thickness: When used as a Primer use a dry coating thickness of at least 10 microns. When used as a One-coat system use a dry coating thickness of at least 15-20 microns. For oil-seal applications a dry coating thickness of 5 microns is typical.

    Drying: After applying Cilbond 10E, components should be left for 30-45 minutes at 25°C to dry properly. Pre-warming at say, 80°C will speed up drying parts.

    Molding Information

    • Cilbond 10E may be processed by all molding methods, including Compression, Transfer, Injection and Extrusion molding and autoclave curing.
    • Temperatures may vary between 130°C and 200°C, which should cover most processes, but tests should be undertaken (preferably by rheometer curve) to produce the optimum cure conditions for compound and bonding agent.
    • Cilbond 10E is capable of withstanding up to 30 minutes pre-bake at 160°C.
    • Cilbond 10E has excellent resistance to wiping and gives excellent bond results on injection molding both high and low acrylonitrile compounds at 150°C and 190°C. It is especially suited to high temperature injection molding.
