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.

Avoid discharge into drains, water courses or onto the ground. Store in tightly closed original container. Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Avoid contact with oxidizing agents. Vulcanises at room temperature on contact with moisture in the air. For further information, refer to Section 10: "Stability and Reactivity". Suitable containers: Steel drums coated with epoxy-resin.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:

  • Primer-less 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.
