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.
