High-Temperature Silicone Sealant 20 ml, Technicqll, black

Technicqll High-Temperature Silicone Sealant 20 ml in black is a silicone-based compound formulated to create flexible, heat-resistant seals and bonds. It is intended for use where joints and components are exposed to elevated temperatures, offering resistance to heat and thermal cycling while maintaining adhesion to a range of common materials. The compact 20 ml tube is suitable for precision applications and repair tasks that require controlled dispensing.

Advantages

This high-temperature silicone provides a combination of heat resistance and flexibility, maintaining a durable seal under thermal stress. It adheres to metals, glass and ceramics and is compatible with selected plastics, enabling repairs and installations across different substrates. The black color allows for discreet sealing in dark assemblies and visible areas. The tube format supports accurate application and minimizes waste for small or detailed jobs.

Suitable for

• Sealing oven doors, furnace access points and heating appliances
• Gasket repair and sealing of engine or exhaust system joints (where silicone is appropriate)
• Sealing and insulating electrical components exposed to heat
• Bonding and sealing glass, ceramic and metal parts in high-temperature environments

Key specifications

• Volume: 20 ml tube
• Color: black
• Base: silicone elastomer formulated for high-temperature resistance
• Application temperature range: suitable for elevated temperatures and thermal cycling (see manufacturer usage limits)
• Curing: acetoxy or neutral cure silicone (creates a flexible elastomeric seal after curing)

How to use

Prepare surfaces by cleaning them of oil, grease, dust and loose particles; ensure surfaces are dry and free of contaminants. Cut the tube tip to the desired bead size and apply the sealant evenly to one surface, then join or compress parts as required. Allow the sealant to cure undisturbed according to ambient temperature and humidity; full curing time depends on bead thickness and environmental conditions. Excess uncured sealant can be removed with a suitable solvent, while cured material must be trimmed mechanically.

Usage recommendations

Do not apply to surfaces that will be continuously immersed in water or to certain plastics that may be sensitive to silicone; verify material compatibility before use. Avoid application on oxidized or contaminated metal surfaces without proper preparation. For electrical insulation or engine applications, confirm the product's specific temperature limits and chemical compatibility with the component manufacturer or technical datasheet.
