High Temperature Sealants

High Temperature Sealants

High Temperature Sealants and mastics are specialized, air-setting refractory pastes used for critical bonding, patching, and sealing applications in extreme thermal environments.

These ready-to-use compounds adhere strongly to metals, ceramics, and brickwork. They cure quickly at room temperature to form a hard, gas-tight seal that is highly resistant to thermal shock, flame impingement, and corrosive fumes. They are widely used for sealing boiler doors, repairing cracked brickwork, and bonding ceramic fiber modules.

• Forms a hard, gas-tight seal resistant to extreme temperatures
• Strong adhesion to a wide variety of substrates (metal, ceramic, brick)
• Ready-to-use paste formulation for easy, immediate application
• Ideal for sealing boiler doors, flues, and repairing cracked masonry
