It maintains stable bonding performance even under continuous high-temperature conditions, making it suitable for demanding industrial furnace environments.
Additionally, Kerui Refractory ensures reliable bonding between ceramic fiber materials and various substrates, including steel surfaces and refractory linings.
Moreover, it withstands rapid temperature fluctuations without cracking, peeling, or loss of adhesion.
Users can apply the adhesive by brush, spray, or trowel; therefore, it is convenient for on-site installation and maintenance.
5. Low Shrinkage & Long Service Life
In addition, the material minimizes shrinkage during drying and heating, which ensures long-term stability and reduces maintenance frequency.
As a result, it effectively seals joints and gaps in insulation systems, reduces heat loss, and improves overall thermal efficiency.

Ceramic Fiber Adhesive is widely used in high-temperature insulation systems where reliable bonding, sealing, and surface protection are required. It plays a critical role in improving the integrity and service life of lightweight refractory linings.
Typical applications include:
Kerui Ceramic Fiber Adhesive is designed to meet different on-site installation and maintenance requirements. Below are typical application solutions in industrial furnaces and thermal equipment:
During installation, workers apply the adhesive to bonding surfaces or anchor contact areas to fix fiber blankets onto furnace casings or steel structures. As a result, this method improves installation efficiency, enhances bonding strength, and keeps the blanket stable under high-temperature conditions and airflow impact.
For rigid insulation structures such as ceramic fiber boards and ceramic fiber modules, the adhesive provides strong and uniform bonding between materials and supporting surfaces. Moreover, it maintains structural integrity, prevents displacement, and improves overall lining stability, especially in vertical or overhead installations.
During maintenance, technicians use the adhesive to repair cracks, reconnect separated joints, or reattach loosened fiber materials. Therefore, they can quickly restore insulation performance without replacing the entire system.
When applied as a coating, the adhesive forms a thin protective layer on ceramic fiber surfaces. In addition, this layer enhances erosion resistance, reduces fiber particle shedding, and improves overall durability.
Proper installation and fixing methods ensure the long-term performance and safety of ceramic fiber insulation systems. Typically, engineers combine refractory anchors with adhesive bonding: anchors provide mechanical support, while the adhesive improves sealing and bonding performance.
