Product Description

The fischer Sanitary Silicone DSSI is suitable for sealing connection and expansion joints in sanitary and kitchen applications. The silicone has 20% elasticity and fungicidal properties, which result in a high resistance to moisture, weather influences and ageing. It is characterised by its ease of use and good adhesion spectrum to a range of surfaces, from stainless steel to ceramics.

fischer Sanitary Silicone DSSI Advantages

  • The 20% elasticity means that the DSSI is ideal for expansion and connection joints. This guarantees long-lasting jointing.
