High-temperature silicone sealant K2 K0477 black 21 g blister pack

High-temperature silicone sealant K2 K0477 in black is supplied in a compact 21 g blister pack designed for focused repairs and sealing tasks. The product is formulated to withstand elevated temperatures and maintain flexibility, making it suitable for sealing small gaps, bonding components and insulating parts exposed to heat. Its small size and thick paste consistency allow application in confined areas and for spot fixes without the need for large cartridges or dispensers.

Advantages

This black high-temperature silicone sealant offers heat resistance and long-term elasticity to accommodate thermal expansion and contraction. The paste provides good adhesion to common engine and metal surfaces, enabling durable seals on exhaust parts, flanges and housings. The blister packaging and 21 g volume are convenient for occasional use and for carrying in a tool kit for maintenance tasks.

Suitable for

• Sealing exhaust joints and manifolds
• Repairing or sealing engine housings and heat-exposed components
• Sealing around heaters, boilers and industrial equipment
• Spot sealing and small bonding jobs in automotive and mechanical maintenance

Key specifications

• Color: black
• Form: silicone paste
• Packaging: 21 g blister pack
• Primary properties: high-temperature resistance, flexible after curing
• Applications: sealing, bonding and insulating of heat-exposed parts

How to use

Prepare surfaces by cleaning and degreasing to ensure good adhesion; remove loose material and old sealant. Apply a small amount of the silicone sealant directly from the blister to the joint or repair area, shaping it as needed before skin formation. Allow the sealant to cure according to ambient temperature and humidity conditions; prevent movement of parts until a functional cure is achieved. Use suitable personal protective equipment and ensure adequate ventilation during application.

Usage recommendations

Store the product in a cool, dry place away from direct sunlight. For best results on metal and engine components, apply on clean, dry surfaces and avoid overapplication that could interfere with mechanical assemblies. For continuous or large sealing work consider using larger-capacity products or compatible application tools.
