Product Description
Spray coating is made of high quality bauxite clinker, clay clinker or lightweight insulation material as the main raw material. Several kinds of binding agents and buffers are added to make high quality spray coating with relatively low rebound rate. It is mainly used for spraying furnace body and pipelines where spraying is needed. It is divided into the following types according to the physical and chemical indicators:
