Silicone sealant Bisan Z6B870296 310 ml — high-temperature resistant up to 1600°C

Silicone sealant Bisan Z6B870296 310 ml is a high-temperature resistant silicone formulated for sealing and bonding in environments exposed to extreme heat up to 1600°C. Supplied in a 310 ml cartridge for use with a standard caulking gun, the product creates flexible, durable seals that maintain adhesion and structural integrity under severe thermal stress. It is intended for repair and maintenance tasks where prolonged or intermittent exposure to very high temperatures occurs.

Advantages

This high-temperature silicone provides stable performance at elevated temperatures and resists thermal degradation, cracking and hardening. The flexible cured seal accommodates differential expansion between dissimilar materials, preserving the joint under cyclical heating and cooling. The cartridge format enables controlled application and reduced waste, while the cured material offers long-term resistance to oxidation and thermal aging.

Suitable for

• Sealing joints in furnaces, ovens and kilns
• Repairing exhaust components and flues
• Sealing around burners, heat exchangers and combustion chambers
• Industrial equipment and domestic appliances exposed to high temperatures

Key specifications

• Heat resistance: up to 1600°C when cured
• Packaging: 310 ml cartridge for caulking guns
• Material type: silicone-based high-temperature sealant
• Cured properties: flexible, heat-resistant, oxidation-resistant

How to use

Surface preparation is important: clean and degrease mating surfaces, remove loose scale, rust or old sealant. Cut the cartridge nozzle to the required bead size and apply the sealant with a compatible caulking gun, pressing the bead firmly into the joint. For best adhesion, apply to dry or minimally damp surfaces and maintain recommended joint dimensions specific to the application. Allow the sealant to cure undisturbed; curing time depends on bead thickness and ambient conditions. Follow general safety precautions and ventilate the workspace if working in confined areas.

Usage recommendations

Use the sealant only within its intended temperature range and avoid continuous mechanical loading beyond joint design. For critical high-temperature applications, test adhesion on representative materials and allow full cure before exposing to peak operating temperatures. Store cartridges in a cool, dry place and use within manufacturer-recommended shelf life.
