Description
Silicon carbide low-cement gunning mix is an unshaped refractory material composed of refractory materials with a specific particle size distribution, chemical binders, and additives, used for repairing the linings of thermal equipment through spray application. Its main components include silicon carbide, low-cement binders and additives. It is characterized by high refractoriness, excellent thermal shock resistance and corrosion resistance, high strength and wear resistance, good adhesion, easy to fast construction and efficient protection.
