    The coating is a two-component viscous paste with a temperature resistance range of - 30-120 ℃. It is a new space energy-saving reflective heat insulation coating with high efficiency, thin layer, heat insulation, decoration, waterproof, fire prevention, corrosion prevention and insulation, The coating is a three-dimensional network infrared thermal energy damping shielding structure which is connected by closed micro nano scale thermal insulation material on the surface of the object.

    There is no peculiar smell or harmful substance in the exterior wall thermal insulation coating under high temperature and normal temperature. The main function of the coating is to prevent heat conduction. The thermal conductivity coefficient is 0.032w/m.k. the coating can effectively inhibit and shield the radiant heat and heat conduction, and the heat insulation inhibition efficiency can reach about 90%. It can inhibit the thermal radiation and heat loss of high-temperature objects, reduce the heat loss and save energy. It can effectively keep cold for low temperature objects, restrain the cooling loss caused by environmental radiant heat, and prevent the generation of condensation water.
    Product features:
    1. High solid content, no organic solvent, environmental protection, non-toxic, suitable for manual or mechanical large-scale spraying, high construction efficiency
    2. It is green and environment-friendly. It adopts the special SPAG airless high-pressure spraying process, which is convenient for construction, saves coatings, and is environmentally friendly and non-toxic,
    3. The thickness of the coating is thin, the thickness is controllable, the thermal insulation performance of the coating is good, and the thermal conductivity is less than 0.032w/m.k (the thermal conductivity of air is 0.03w/m.k). The extremely low thermal conductivity of the building exterior wall thermal insulation coating can save more than 30% of energy waste in high cold or high heat areas.
    4. The exterior wall thermal insulation coating has toughness and high fracture elongation. The polymer material contains labyrinth hole effect, which has outstanding damping and sound insulation effect. The indoor noise can be reduced to below 45 dB with double insulating glass, which greatly reduces the noise pollution.
    5. Functional modified nano thermal insulation material and high molecular weight polymer are used in the thermal insulation coating of building exterior wall to strengthen the thermal insulation performance and improve the energy utilization rate.
    6. The coating has good adhesion, high temperature cold and hot shock resistance, good thermal shock resistance, heat insulation and anti-corrosion, and has a certain anti shock and anti shock strength.
    7. The thermal insulation coating of building exterior wall contains corrosion-resistant functional materials, and the coating is resistant to acid and alkali corrosion.
    8. The thermal insulation coating of building exterior wall has good anti ultraviolet aging and anti-oxidation function. The color of the material will not change after spraying on the surface of the building for a long time, and the color retention rate is very prominent.

    Application fields:
    The product mainly adopts the film-forming materials with good weather resistance, water resistance, aging resistance, strong adhesive force and elasticity, and good compatibility with thermal insulation filler and reflective filler. It selects the filler with light weight, hollow, high temperature resistance, high thermal resistance, good reflection and radiation, and the ultra-fine powder with high refractive index, high surface finish, high thermal reflectance and emissivity The low radiation heat transfer layer is composed of reflective filler and film-forming substrate, which can effectively block the heat transfer. The product can be used for a long time in the range of service temperature. It is not easy to be aged, deteriorated, nontoxic and tasteless. It has the characteristics of light weight, small thermal conductivity, cold insulation, heat insulation, shock proof and sound insulation. It can be widely used in metallurgy, chemical industry, petroleum, shipping, transportation, thermal power, construction and other industries. It is convenient for construction, does not pollute the environment, and has no loss in construction. In the field of construction engineering, it is mainly used in the heat insulation occasions, that is, the high reflective heat insulation coating is used on the surface of the exterior envelope, which can reduce the absorption of solar radiation heat by the building exterior wall, prevent the temperature rise caused by the absorption of solar radiation on the surface of the building exterior wall, and reduce the heat into the room.
