Ceramic fiber spray coating application for furnace insulation

Ceramic Fiber Spray Coating for Seamless Furnace Insulation

Advanced spray-applied insulation for repairs, complex surfaces, and narrow spaces

🔥 Up to 1400°C 🎯 Seamless Application 🔧 Easy Repairs 🔇 Sound Absorption

Ceramic Fiber Spray Coating is an innovative insulation technology developed from ceramic fiber and modern spray application techniques. High-quality ceramic fiber is processed through specialized fiber spray equipment, using high-pressure air to deliver the fiber to the spray nozzle, where it mixes with atomized binder to form a seamless insulation layer on the hot face surface. This product provides excellent integrity, no joints, and superior insulation performance, making it ideal for special areas, narrow spaces, furnace repairs, and maintenance applications.
