Process
- Particularly suited to processes involving hot press and cure within the mould
- Cilbond 63W (R-7159) must be completely dry before moulding. Apply Cilbond 63W (R-7159) to pre-heated metal parts (35 -50°C). Metals can also be put in an oven after coating, but do not exceed 50°C. If applying to unheated metal parts, the ambient temperature should ideally be above 20°C and allow films to dry for at least 60 minutes.
- Pre-baking could reduce penetration into the friction compound, and so is not recommended for brake pad bonding.

- Usage Information
-
Agitation: It is necessary to stir Cilbond R-7159 gently yet thoroughly before use. Avoid creating froth or foam, but if foaming does occur, stir slowly until reduced to a minimum. Cilbond R-7159 should also be stirred occasionally during use and for large scale production runs, stirred continuously. Note that the product may thicken on long-term standing. If thickening does occur, stir gently yet thoroughly.
Roller-coating: The viscosity of Cilbond R-7159 is designed to be applied by Roller Coating, so dilution may only be necessary in some cases.
Brushing: Cilbond R-7159 can be brush applied without the need for dilution. If improved flow is required dilute with 10 - 20 % deionised water by weight.
Spraying: For Spray Application, consider using Cilbond 62W (1,500 cps) which is formulated to be sprayed as supplied. It is possible to spray Cilbond R-7159 but we recommend it is diluted to a viscosity of 25 - 40 seconds on a DIN 4 or Ford 4 cup using the minimum amount of deionised water to give an excellent spray pattern. For conventional air pressure spray systems, a fluid pressure of 0.5-1.0 bar is typical whilst the air pressure is typically 2-3 bars, dependent on the fineness of the spray required and the initial temperature of the metal. Always endeavour to use the lowest possible gun air pressure. A nozzle size of at least 1.2 mm is recommended and nozzle size of ca. 2mm is typical for most applications.
Dipping: Dilute Cilbond R-7159 to give a viscosity within the range of 30 - 45 seconds on a DIN 4 or Ford 4 cup using the minimum amount of deionised water (typically 10 - 20% by weight) and stir continuously. Avoid frothing or foaming.
Dilution: Recommended diluents include deionised water, distilled water or deionised water/alcohol blends, but the alcohol level in any pre-mixed diluent should be at <<10%
Coating: The above recommendations should give the optimum dry coating thickness for Friction
Thickness: bonding of 20 – 30 microns.
​​​​​​​Drying: It is very important to ensure the Cilbond R-7159 is completely dry before moulding. Any retained water may cause blisters during the moulding cycle, leading to cement to metal failure and reduced corrosion resistance. Apply Cilbond R-7159 to pre-heated metal parts (35 - 50°C). Metals can also be put in an oven after coating, but do not exceed 50°C.
If applying to unheated metal parts, the ambient temperature should ideally be above 20°C and allow films to dry for at least 60 minutes. When applying to grit blasted metals, pre-heating or heating after coating to above 20°C may be essential to prevent surface defects such as lack of film coalescence, which may manifest itself as brown resin spots. Although this is unlikely to affect bonding, it could possibly affect long-term in-service environmental resistance properties and could lead to reduced pad
penetration. It is also possible to dry the coating with cool forced air, provided the humidity is not too high.
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 that are fully dried may be stored for a period of several weeks, provided they are protected from dust, oil vapours and water.
Cleaning: Equipment should be cleaned using water or water containing detergent. If the Cilbond R-7159 has dried to a hard film use MEK or MIBK as the cleaning solvent. Before using Cilbond R-7159 it is very important that any previous material is thoroughly cleaned out. When visibly clean, wash through with MEK or acetone, particularly the spray heads and nozzles. Finally, flush through with deionised water until all traces of ketone solvent are removed. This is vital, as ketones will cause Cilbond R-7159 to gel.

Storage & Handling
- Storage Condition
-
- Cilbond® 63W should be stored / transported between 0 °C and 30 °C.
- If stored above or below these temperatures, then we recommend validating the material to ensure it still meets end-use require- ments. If stored below -5 °C, warm slowly and then stir with a high shear to form a smooth and homoge- nous mix.
- If stored above 40 °C, then cool as soon as possible, re-check that the product is with original specification and use with 1 month.
- Storage Information
-
- Avoid storing Cilbond R-7159 at temperatures below -5°C. If freezing does occur, warm slowly, shake container and finally stir with a high shear for the minimum time to form a smooth and homogenous mix.
- Cilbond R-7159 is free from lead and virtually free from solvent and is supplied in 10 litre, 25 litre containers and 200 litre stirrer drums. 250ml trial samples are also available upon request.
