CAF 520 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 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 onto clean & dry surfaces.

CAF 520 TRANSLUCENT 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 is a one component silicone elastomer curing at Room Temperature:

  • Neutral
  • Self-adhesive
  • Thixotrope
  • Translucent, white



1 Part RTV Alcoxy

CAF 520 combines the advantages of:

  • Primerless adhesion.
  • Odourless, it is particularly well accepted in the workstation environment.
  • High cure rate.

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


CAF 520 is a fast-curing, ready-to-use silicone elastomer suitable for sealing and bonding. It cross-links at room temperature to give a flexible seal.
CAF 520 is used for following applications:

  • Sealing and bonding of plastic materials.
  • Bonding of headlight.
  • Industrial maintenance.
  • Domestic appliances.
  • Electronics.
  • Solar panels.
