High-temperature silicone paste K2 B2450, red, 21 g, withstands up to 350°C

High-temperature silicone paste K2 B2450 in red is a compact 21 g tube of heat-resistant silicone compound designed for sealing, lubricating and protecting components exposed to elevated temperatures. The paste maintains its properties at temperatures up to 350°C, offering thermal stability and electrical insulation where standard silicones would fail. Its consistency allows precise application to gaskets, threads, flanges and small mating surfaces in automotive, industrial and household equipment.

Advantages

The red silicone paste provides reliable performance at high temperatures, remaining stable and adherent under thermal cycling. Its formulation offers good dielectric properties and resistance to oxidation and aging, reducing the need for frequent maintenance. The small 21 g tube delivers controlled dispensing for repair and assembly tasks while minimizing waste.

Suitable for

• Sealing exhaust components and heat shields in automotive systems
• Protecting and insulating electrical connections exposed to heat
• Gasketing and flange sealing in industrial equipment operating at high temperatures
• Thread protection for fasteners subject to thermal expansion
• Localized repairs and maintenance in household appliances with high-temperature parts

Key specifications

• Color: red
• Form: paste in a squeezable tube
• Net content: 21 g
• Maximum continuous service temperature: up to 350°C
• Thermal stability suitable for cyclic high-temperature exposure
• Electrical insulation properties suitable for general-purpose use
• Resistance to oxidation and aging at elevated temperatures

How to use

Ensure mating surfaces are clean, dry and free from oil, grease or loose particles before application. Apply an even, thin layer of the silicone paste to the sealing surface, thread or component to be protected. Reassemble parts and allow the compound to cure according to ambient temperature; full mechanical and thermal resistance develops after curing. For electrical insulation, apply to fully de-energized components and allow adequate cure time before re-energizing.

Usage recommendations

Use the paste in well-ventilated areas and avoid contact with eyes and skin. Store the tube tightly closed in a cool, dry place away from direct sunlight. For best results, test compatibility with plastics and painted surfaces on an inconspicuous area before wide application. Do not use on components intended for continuous immersion in liquids unless specified by the equipment manufacturer.
