Description
- TOP QUALITY GASKET MAKER/SEALER.
- 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
properties.
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.
