Nano Waterborne Solar Thermal reflection Coatings

A nano water-based solar heat reflective coating has been studied, and it has been found through testing that the solar reflective coating prepared with composite inorganic black pigments has excellent solar reflectance, and adding suitable nano-silica concentrated slurry can significantly improve the solar reflectance of the coating. Key words: nano-silica concentrated slurry; solar reflectance; pigment; filler.

in conclusion

(1) The coating prepared with inorganic composite black pigment has excellent solar reflectance; 

(2) The filler has little effect on the solar reflectance of the coating. 

(3) Appropriate amount of concentrated nano-silica slurry can significantly improve the solar reflectance of the coating.
