Cilbond® 10E

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.

In-service Benefits:

• ​​​​​The extremely tough dry films of Cilbond 10E means that coated components can be subjected to considerable 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 130°C and 200°C) and has excellent pre-bake resistance (up to 30 minutes at 160°C)

​​​​​Processing 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 35°C, 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.

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.
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.
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.
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.
Uniform Coatings: The key to successful bonding with Cilbond 10E is uniform coatings at the optimum film thickness. At the viscosities suggested above, a satisfactory film thickness should result. However, laboratory tests are always advised to assess the practical film thickness for production conditions.
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.

Pre-baking: Pre-baking could reduce penetration into the friction compound, and so is not recommended for brake pad bonding. However it is important to ensure the coating is completely dry. If not, the retained water may cause blisters. See Drying Section above.
Storage: Coated parts may be stored for long periods of time (several weeks) provided they are protected from dust, oil mists, mould release over-spray and moisture.

Where to use:
Cilbond 10E is used as a one-coat system and also as a two-coat system (with Cilbond 80ET) to produce :
