Sealant CX80 silicone high-temperature red 310 ml (CXSCZERWONY310)

CX80 silicone high-temperature red 310 ml is a single-component silicone sealant formulated to withstand elevated temperatures while maintaining elasticity and adhesion. Supplied in a 310 ml cartridge for use with a standard caulking gun, this red sealant is intended for heat-exposed joints, flange connections and repairs where a flexible, long-lasting seal is required. The product is suitable for automotive, heating, oven and exhaust system applications and can be used to fill gaps and bond surfaces that encounter repeated thermal cycling.

Advantages

This high-temperature silicone offers heat resistance combined with retained flexibility, ensuring seals remain elastic under thermal stress. Its one-component formulation requires no mixing and cures at room temperature to form a durable, weather- and water-resistant joint. The red color provides visual identification in repair and assembly tasks, and the cartridge format allows controlled application with common caulking guns for accurate bead placement.

Suitable for

• Automotive exhaust joints and flange sealing
• Sealing around ovens, stoves and heating appliances
• Repairing and sealing hot-air ducts and ventilation components
• High-temperature gasketing and gap filling in industrial equipment

Key specifications

• Formulation: single-component silicone
• Color: red
• Volume: 310 ml cartridge
• Application method: manual caulking gun
• Properties: heat resistant, elastic after cure, water-resistant

How to use

Ensure mating surfaces are clean, dry and free of oil, grease and loose particles before application. Cut the cartridge tip to the desired bead size and fit a compatible nozzle. Apply the silicone evenly into the joint or onto the flange using a standard caulking gun, ensuring full contact with both surfaces. Tool the bead if necessary within the skinning time to achieve a smooth finish. Allow the sealant to cure at ambient conditions; curing time depends on bead size and environmental humidity.

Usage recommendations

For best performance on high-temperature applications, allow full cure before exposing the sealant to continuous elevated temperatures and avoid painting over the cured silicone with incompatible coatings. Use appropriate personal protective equipment during application and follow ventilation guidelines in confined spaces.
