High-temperature silicone sealant GEKO 80 g, red

High-temperature silicone sealant GEKO 80 g in red is a temperature-resistant silicone paste formulated for sealing, bonding and repairing joints and surfaces exposed to elevated heat. The product is supplied in an 80 g cartridge and is intended for use on metals, glass, ceramics and many construction materials where an elastic, heat-resistant seal is required. It is suitable for applications such as ovens, furnaces, exhaust components and other equipment operating at high temperatures where a red-coloured silicone provides both functional sealing and visual identification.

Advantages

This GEKO high-temperature silicone sealant maintains elasticity and adhesion under thermal stress, providing durable seals that resist cracking and shrinking. Its red colour offers clear visual identification of treated areas and can match or complement components requiring colour-coded sealing. The sealant bonds to a range of substrates including metal, glass and ceramic, and cures to a flexible, heat-stable bead that withstands repeated heating cycles.

Suitable for

• Sealing oven and furnace joints
• Repairing exhaust systems and heat shields
• Sealing flanges and metal-to-metal joints exposed to heat
• Sealing around heating elements, stoves and boilers
• Bonding or sealing ceramic and glass components in high-temperature environments

Key specifications

• Colour: red
• Packaging size: 80 g cartridge
• Material type: high-temperature silicone
• Properties: elastic after curing, heat-resistant, adhesion to metal, glass and ceramics
• Application temperature range: suitable for high-temperature applications (see manufacturer guidelines for limits)

How to use

Prepare surfaces by cleaning them of oil, grease, dust and loose particles. Cut the cartridge tip and apply the sealant using a suitable applicator or gun, forming a continuous bead along the joint or repair area. Tool the bead as needed to ensure good contact with the substrate and a neat finish. Allow the sealant to cure according to ambient temperature and humidity; full performance is achieved after complete curing. Follow safety and ventilation recommendations when working in confined or poorly ventilated spaces.

Usage recommendations

For best results, test compatibility on a small area before full application, and consult equipment specifications for maximum service temperatures. Do not apply to wet or contaminated surfaces; ensure adequate curing time before exposing the seal to full operational temperatures.
