Application Guidelines

Cilbond R-7189 must be stirred well before use

Cleaning Information

Clean tools immediately after use.
Once cured, the material can only be removed mechanically.
Appropriate cleaners are listed in the product properties table.
Cleaner for Tools
- Water
- Dried material can be removed with methyl ethyl ketone (MEK)

Preparation Information

For some substrates pretreatment is necessary to achieve good adhesion.
Refer to the product prop- erties section of this data sheet for special surface requirements and suitable adhesion promoters.
It is necessary to stir Cilbond R-7189 gently, yet thor- oughly before use. Avoid creating froth or foam, but if foaming does occur, stir slowly until reduced to a minimum. Cilbond R-7189 should also be stirred oc- casionally during use and for large scale production runs, stirred continuously.
Surface Requirements - Free of rust, Grit blasted or other approved surface treatments, Clean, Free of grease, Free of dust, Free of oil

Processing Information

Particularly suited to processes involving hot press and cure within the mould Cilbond R-7189 must be completely dry before moulding. Apply Cilbond R-7189 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.
Suitable Substrates - Various surface treated metals and Various metals

Storage Information

Cilbond R-7189 should be stored / transported be- tween 0 °C and 30 °C.
If stored above or below these temperatures, then we recommend validating the ma- terial to ensure it still meets end-use requirements.
If stored below -5 °C, warm slowly and then stir with a high shear to form a smooth and homogenous 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.
