Silcolease 7611 is normally formulated as a 3 component system for easy compounding and use. The standard formulation and processing (order of addition) is;

1. Dilution solvent: Quantity depends on the desired bath solids (aliphatic or aromatic) ,100 to 600 pts

2. Silcolease 7611: 100 pts;

3. Mix thoroughly to disperse completely(time varies with the equipment)

4. Silcolease crosslinker 321: 1.6 pts;

5. Silcolease catalyst 91B: 3.7 pts(up to 6pts)

6. Mix thoroughly to ensure full dispersion of the catalys.

It is also possible to formulate Silcolease 7611 as a multi-component system with other additives to modify cure, substrate anchorage or release performance if necessary. Details of these formulations can be provided on request

SILCOLEASE 7611 may be stored at a temperature between -20 °C/ -4 °F and 30 °C/ 86 °F for up to 12 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


​A kind of tri-component solventless type paper release system:

  • Silcolease 7611 (base polymer)
  • Silcolease crosslinker 321(crosslinker)
  • Silcolease catalyst 91B (catalyst)


Vinyl Functional Fluid


  • Need less solvent

  • Cure st relative low temperature

  • Low levels of silicone migration

  • Good bath stability(catalyzed)

  • Low and stable release values against a wide range of aggressive adhesive types

  • Excellent performance for cure and anchorage on a wide range of substrates

  • Good resistance to inhibition effects from a wide range of substrates

The system is designed specifically for Paper Release applications and can be coated onto a wide range of paper, film and foil substrates. The system must be diluted to a chosen concentration with a suitable solvent for coating onto the desired substrate. After application to the substrate the coating requires a short heat schedule to remove the solvent and cure the silicone.
