The nano thermal insulation and waterproof integrated coating is a radiation-type thermal insulation paint based on ultra-fine particle size organosilicon copolymerized acrylic. The coating contains a large amount of inorganic metal oxides, polycrystalline compounds, and thermal control technology. It boasts excellent outdoor weather resistance, self-cleaning properties, adhesion, coating elasticity, high-temperature resistance without softening, and low-temperature resistance without brittleness. It is particularly suitable for scenarios such as roofs, exterior walls, pipelines, and oil pipelines, meeting the needs of thermal insulation, cooling, waterproofing, anti-corrosion, and decorative renovation. The coating can reflect more than 90% of solar heat, reducing roof temperature. With an emissivity of over 90%, it rapidly dissipates heat accumulated on the roof, keeping the roof cool.
