Processing is performed easily in a horizontally rotating drum, proceeding in the following manner (for information purposes only):

  • Dust removal from the corks by tumbling for around 10 minutes dust is extracted.
  • Adding of SILBIONE CAF 72589 (manually or sprayed).
  • Dosage (for information purposes): 180 g to 270 g for 10000 corks sized 48x30.5 (agglomerated cork).
  • Tumble in the drum for 20 minutes. It is recommended to work in a workshop at a room temperature of 20-25 °C and a relative humidity of around 50%.
  • Air drying or storage in perforated plastic bags.
  • Conditioning for at least 24 hours before delivering.

If the corks have been subjected to a prior treatment to lubrication (for example bleaching, tinting, waxing, …), the user must ensure that there is no incompatibility between residues of this prior treatment and the SILBIONE CAF 72589, which could cause problems of adhesion or lubrication.


SILBIONE CAF 72589 may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 18 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


SILBIONE CAF 72589 is a one component silicone elastomer, curing at room temperature on contact with atmospheric humidity, used to treat natural or agglomerated bottle corks.
SILBIONE CAF 72589 is a solventless product based on reactive polymethyl siloxane oils and inert fillers. It can be used as a release coating for materials intended for food contact.
