Description
TOP QUALITY GASKET MAKER/SEALER.
Description and applications
Dirko™ HT Grey (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 Grey 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.
