CAF 72589 is a one-component, moisture-curing silicone for the release coating of bottle corks.
It belongs to Elkem's Silbione range and is a solvent-free coating based on reactive polydimethylsiloxane oils. When applied, it forms a very thin, non-stick silicone film that improves the smoothness and sealing action of corks.
CAF 72589 is not a sealant, but a thin non-stick and release coating for natural and agglomerated bottle corks. According to the Elkem data sheet, it can be used as a release coating for materials that come into contact with food.
