CAF 520 S is ready to use.

Processing is particularly easy, since the products are delivered ready to use. Application can be carried out either manually or using robotic application equipment.

CAF 520 S is applied to one of the two joint surfaces and assembled before the product has formed a skin.

It is recommended to apply CAF 520 S onto clean & dry surfaces.

The time until complete curing may be extended at lower temperature, lower humidity, increasing film thickness or by low volume of air exchange.

CAF 520 S WHITE may be stored at temperatures 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.


CAF 520 S is a one component, neutral (alkoxy), silicone elastomer curing at room temperature which is protected by a fungicide:

CAF 520 S combines the advantages of:

  • Primer-less adhesion
  • High cure rate

    Its mechanical properties and good adhesion to many surfaces allow perfect assembly and full sealing between materials of different types such as glass, metals, ceramics and plastics.

The cured product is also resistant to fungal growth in hot humid environments

CAF 520 S is a fast-curing, ready-to-use silicone elastomer suitable for sealing and bonding. It cures at room temperature to give a flexible seal.

CAF 520 S is used for sealing and bonding applications in the following fields: domestic appliances, solar panels, marine, industrial maintenance especially where a protection against degradation and mould is desired
