High-temperature silicone sealant K2 C1-K1092 red, service temperature up to +350°C, 85 g

High-temperature silicone sealant K2 C1-K1092 red is a 85 g cartridge formulated to form flexible, heat-resistant joints and fill gaps where temperatures rise up to +350°C. Designed for applications that require stable performance under high thermal stress, this sealant adheres to metal, glass and ceramics and maintains elasticity after curing. The red color makes it suitable where a visible seal is required or where color-coding of serviceable parts is preferred.

Advantages

The formulation provides durable heat resistance up to +350°C while retaining flexibility to accommodate thermal expansion and vibration. It bonds to common high-temperature substrates such as metal, glass and ceramics without hardening into a brittle state. The cartridge size (85 g) is convenient for repair and maintenance tasks and allows controlled application in tight joints and around exhaust or engine components.

Suitable for

• Sealing exhaust system joints and flanges on vehicles
• Gasketing and minor repairs on engine components exposed to high heat
• Sealing ovens, grills and industrial heating equipment
• Repair and sealing of metal, glass or ceramic parts in high-temperature environments

Key specifications

• Color: red
• Net content: 85 g cartridge
• Service temperature range: up to +350°C
• Material type: high-temperature silicone elastomer
• Properties after cure: flexible, heat-resistant, gap-filling

How to use

Ensure surfaces are clean, dry and free of oil, rust or loose particles before application. Cut the cartridge tip to the desired bead size and apply using a suitable caulking gun. Smooth the sealant within a few minutes if required and allow it to cure according to ambient temperature and humidity; full properties develop after complete curing. Avoid applying to surfaces where pressure-tight sealing under liquid immersion is required unless specified for that use.

Usage recommendations

Use on clean metal, glass or ceramic surfaces and allow adequate curing time before exposing the sealed joint to full operating temperature. For automotive exhaust or engine repairs, inspect the joint after initial heat cycles and re-tighten any mechanical fasteners if necessary. Store the cartridge in a cool, dry place and keep out of reach of children.
