SILCOLEASE ADD 702 is added to the SILCOLEASE emulsion formulated bath at doses that will depend on application method, end-use and bath concentration.

At higher levels of addition drying performance will be impacted and viscosity of the bath will be increased significantly.

Typically the product is used in the following applications:

  • On-paper machine (reduced drying capacity) between 50 to 150 ppm.
  • On-paper machine (high drying capacity) between 50 to 500 ppm.
  • Off paper machine applications (high drying capacity) between 100 to 1000 ppm.

While SILCOLEASE ADD 702 is fully water soluble the dilution process needs careful attention.

The powder as supplied cannot be easily incorporated directly into the coating bath and it is strongly recommended to pre-dilute the SILCOLEASE ADD 702 powder as part of the dilution water to be used.

Only dilute (<1%) solutions of SILCOLEASE ADD 702 can be easily handled due to the very high viscosity effects.

The powder is fully water soluble but care must be taken in the dilution process. Full recommendations for diluting the SILCOLEASE ADD 702 powder are given in section 8 of the SILCOLEASE ADD 702 Technical Information Sheet.

For this document and more detailed information on the use this product and its incorporation into the silicone emulsion bath, please contact your local Bluestar Silicones Technical Service Representative.

SILCOLEASE ADD 702 may be stored at temperatures between 0°C / 32°F and 30°C / 86°F for up to 24 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILCOLEASE ADD 702 is a white, granular powder, freely soluble in water and possessing a slight odour of ammonia.

It is used with emulsion SILCOLEASE polyaddition or polycondensation release systems to improve hold-out of the silicone.

​SILCOLEASE ADD 702 is a non-silicone additive which can offer improved performance to our SILCOLEASE emulsion range. In particular, it has been shown to:

  • Improve shear resistance of emulsion, extend bath life and stability on machine
  • Reduce penetration into porous papers thus potentially lower silicone consumption
  • Reduce foaming and splashing on size press
  • Improve release performance
