Antimony Tin Oxide (ATO) nanoparticles work as sunlight heat shields in the near infrared region (NIR) region of solar radiation and are also used to protect acid sensitive materials. They are commonly used in protective coatings due to its optical transparency.

The flexibility of polysilazane matrixes allows the creation of coatings with beneficial ATO properties, such as high mechanical strength and thermal stability with good optical, thermal and barrier properties. The use of ATO will help to reduce chemical reactions of contaminants aggravated by heat and UV that can otherwise result in etching, water-spotting and staining
