Inorganic fiber coating is a new type of environmentally friendly building paint, primarily composed of inorganic fibers and water-based adhesives. After mixing, it is sprayed through an air compressor and combined with atomized water, creating a coating on the base material that needs protection. This coating meets requirements for sound absorption, thermal insulation, and fire protection. The material is lightweight, odorless, non-toxic, has good sound absorption and weather resistance, provides efficient thermal insulation, and is reliable in fire resistance, achieving over 5 hours of high fire resistance protection. It is suitable for fire protection of buildings and tunnels, especially for high-rise steel structures with strict fire resistance requirements, as well as for the thermal insulation and sound absorption of buildings and energy-saving insulation of machinery and equipment.
