Producer

  • ESPE

Materials

  • metal, ceramic
  • pre-treatment for metal ceramic and metal polymer composites in dentistry

Available blasting abrasives

  1. surface preparation: ROCATECTM PRE high purity corundum (110 µm)
    → cleaning and activation of surface and standardization of surface roughness
  2. silica coating: ROCATECTM PLUS corundum (110 µm) with alkoxysilane
    → production of a SiOx-film (tribochemical reaction)
  3. primer: ESPE SIL
    → improvement of the surface activity

Applications

  • silica coating of joint surfaces (tribochemical method)
  • cleaning, roughening and blast coating
