Applications & Uses
- Product Applications
-
- Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
- Refer to the technical data table regarding processing parameters.
- Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
- Depending on the construction of the equipment, a continuous heating above pro- cessing temperature can cause decomposition of the adhesive.
- Tank melters should use protective gases with < 5 ppm humidity, only. Rakoll" 4654 is moisture sensitive, therefore container must be kept closed.
- Clean tools immediately after use.
- Once cured, the material can only be removed mechanically.

- Product Benefits
-
Versatile application conditions:
- Shows high initial strength and fast setting which makes the product ideal for difficult to bond substrates.
- Low application temperatures from +120°C allow bonding of more heat sensitive materials. It also potentially provides energy cost savings.
- Suitable for profiles with tight curvatures.
Temperature resistance:
- High heat resistance after complete curing up to 150°C depending on the surface materials
- Good cold resistance
