Compatible Materials

Vitcas Heat Resistant Sealant can seal, fix and join a range of compatible high-temperature materials, including:

• Ceramics
• Glass
• Metal
• Silica-based materials
• Other suitable heat-resistant surfaces

Surface treatments and different material grades may affect adhesion. Therefore, test the sealant on a small hidden area when you are unsure about compatibility.

Suitable Applications

Use this high-temperature sealant for suitable applications such as:

• Sealing thin joints exposed to high temperatures
• Jointing compatible ceramic components
• Sealing suitable metal components
• Fixing compatible glass and silica-based materials
• High-temperature caulking work
• Suitable fire-protection installations
• Domestic heating and fireplace applications
• Industrial furnaces and thermal equipment

Always confirm that the materials, joint design and operating temperature suit this sealant before starting the work.

How to Apply Vitcas Heat Resistant Sealant

1. First, make sure the appliance and application area are completely cold.
2. Remove all dirt, dust, rust, grease and loose material from the surfaces.
3. Make sure the joint is clean and correctly prepared.
4. Cut the top from the cartridge and attach the nozzle.
5. Trim the nozzle to produce the required bead size.
6. Fit the cartridge into a standard sealant gun.
7. Apply the sealant directly into the joint.
8. Aim for a thin joint of approximately 2–3mm.
9. Tool and smooth the sealant before it begins to set.
10. Clean away unwanted material promptly.
11. Allow the sealant to set at room temperature.
12. Finally, introduce heat gradually over approximately four hours to complete the curing process.

Drying and Curing

The sealant sets at room temperature. However, drying and curing times can vary according to the temperature, humidity, joint thickness and surrounding materials.

You can speed up the final cure by applying heat gradually over approximately four hours. Do not expose the fresh sealant to full operating temperature immediately because a rapid increase in heat may damage the joint.

Finishing the Sealant

Once the sealant has dried and cured fully, you can sand it to improve the finished surface. You can also overpaint the cured sealant with a suitable, compatible paint.

Before painting, make sure the surface is dry, clean and free from dust. Test the paint on a small area if you are unsure about compatibility or heat resistance.

Important Installation Information

• Only apply the sealant to cold surfaces
• Clean and prepare every surface before application
• Use for thin joints of approximately 2–3mm
• Do not exceed the maximum temperature rating of 1300°C
• Allow the sealant to set before applying heat
• Introduce heat gradually during the final curing process
• Do not use as a substitute for a flexible movement-joint sealant
• Confirm material compatibility before installation
• Follow all application and safety instructions on the packaging
