- Usage Information
Agitation: Cilbond 89ET must be thoroughly stirred before use, preferably with a propeller type agitator.
Brushing: Cilbond 89ET can be brush applied without the need for dilution. If dilution is required (if covering large areas) use Xylene or Toluene.
Spraying: To apply by spray, dilute with Toluene or Xylene to a viscosity of 23 - 26 seconds (Zahn No. 2 cup at 25°C) or 16 - 20 seconds on a DIN 4 / Ford 4 / Frikmar Cup at 25°C.
If cob-webbing (fibrillation) occurs on spraying, replace the Toluene with Xylene. A nozzle size of 1.0 - 1.5mm is recommended, with an air pressure of 1.5 bar.
Note : Excessive pressure can lead to cob-webbing. Cilbond 89ET contains an isocyanate prepolymer of very low volatility. This is reactive towards water and so extra care must be taken when spraying.
Dipping: For Dipping, dilute with Toluene or Xylene to a viscosity of 23 - 26 seconds (Zahn No 2 cup at 25°C) or 16 - 20 seconds on a DIN 4 / Ford 4 / Frikmar Cup at 25°C.
Dilution: CIL recommends Xylene or Toluene to dilute Cilbond 89ET.
Coating thickness: As a One-Component bonding system apply at a dry film thickness of 15 – 30 microns. As a Cover-Coat bonding system apply at a dry film thickness of 10 – 25 microns.
Drying: Allow 20 - 30 minutes drying time at room temperature. Pre-warming parts to ~60°C prior to coating will reduce the drying time.
Pre-baking: Pre-baking Cilbond 89ET is not normally recommended, but short pre-bakes of up to 10 minutes at ca. 155°C can be tolerated, if necessary.
Storage: Parts coated with Cilbond 89ET should ideally be bonded within 30 hours of drying. Allowing the coated parts to air-cure for longer than 30 hours can improve substrate
adhesion and resistance to wiping (melt-flow) and mould fouling. However, depending on the elastomer, this may also result in a gradual reduction in elastomer adhesion. Tests at CIL have shown that parts coated with Cilbond 89ET may be stored for up to 14 days (in a clean, dry environment) without a reduction in adhesion, but full customer validation is recommended.
Moulding: Cilbond 89ET can be processed by all conventional moulding techniques and it exhibits good bonding within the temperature range of 70°C – 180°C.- Processing Information
