  • Description and applications
    Dirko™ HT red (acetic curing) is a high-quality, high
    temperature resistant single component silicone-based
    sealing compound that exhibits permanently resilient
    It provides excellent adhesion on all standard metals, cast iron, plastics (except for PE, PP and
    PTFE) and glass. Due to a reaction with humidity in the air Dirko™ HT red cures to form silicone.
    The product can be used for a very wide range of applications.

General information

Usage and processing instructions:

  • 1. Remove sealant residues and clean the sealing surfaces with solvent.
  • 2. Sealing surfaces must be clean, dry, and free of oil or grease before applying the sealing
    compound in order to ensure reliable sealing and adhesion.
  • 3. Processing temperature (ambient / adhesion surface temperature): +5 to +35°C
  • 4. Apply the sealing compound evenly across the entire surface.
  • 5. Immediately remove any excess sealing compound applied, as there is a risk that it could
    drip into the interior.
  • 6. Depending on the application, the parts can be fitted immediately after application, after
    skin formation or after complete curing.
  • 7. Fit the components in line with the manufacturer’s specifications.
  • 8. The sealing function is immediate.
  • 9. After use, reseal the sealing compound securely.
