How to Use Dirko HT Silicone Sealing Compound Grey

Proper application of Dirko HT is essential for achieving optimal results. Follow these steps for a successful sealing job:

1. Surface Preparation

• Ensure the surface is clean, dry, and free of oil, grease, dirt, and old sealant.
• Use a solvent like acetone or isopropyl alcohol to clean metal surfaces.

2. Application

• Cut the nozzle of the tube to the desired bead size.
• Apply a continuous bead of Dirko HT to one surface, ensuring even coverage. For larger areas, spread the compound with a spatula if needed.

3. Assembly

• Assemble the components immediately after applying the sealant. The compound remains workable for 5–10 minutes, depending on humidity and temperature.

4. Curing

• Allow the sealant to cure for 24 hours at room temperature. Curing times may vary depending on the thickness of the bead and environmental conditions.

5. Final Inspection

• After curing, inspect the seal for uniformity and integrity. Remove any excess sealant with a sharp blade or solvent.

Maintenance and Storage Tips

1. Storage:
   • Keep the tube tightly sealed when not in use to prevent premature curing.
   • Store in a cool, dry place away from direct sunlight and heat sources.
2. Shelf Life:
   • Dirko HT typically has a shelf life of 12–18 months if stored properly. Check the expiration date on the packaging.
3. Usage Precautions:
   • Avoid contact with skin and eyes. Use gloves and ensure adequate ventilation during application.
   • Do not use in areas exposed to pure oxygen or highly oxidizing chemicals.

Comparison with Other Sealants

Dirko HT stands out compared to other sealants due to its unique combination of properties:

Common Issues and Troubleshooting

1. Incomplete Curing:
   • Cause: Low humidity or insufficient curing time.
   • Solution: Allow more time or increase ambient humidity slightly.
2. Weak Bonding:
   • Cause: Contaminated surfaces or incorrect application.
   • Solution: Clean surfaces thoroughly and reapply the sealant.
3. Excess Sealant:
   • Cause: Over-application.
   • Solution: Remove excess with a solvent or a plastic scraper before curing.

Environmental and Safety Considerations

Dirko HT is designed to minimize environmental impact. Its neutral-curing formulation reduces the release of harmful substances during application. However, proper disposal of used or excess sealant is essential to avoid environmental contamination. Always follow local regulations for waste disposal.
