Japan Cement has developed various metal oxide ultra-fine powders by utilizing new ultra-fine powder manufacturing technology. Our metal oxide used in "Nippon Tint" has excellent absorption characteristics over a wide wave length range. This includes near infra-red (780nm to 2,500 nm) to far infra-red (longer than 2,500nm) wave length. "Nippon Tint" film is excellent in heat shielding, transparency, and durability and has been successfully developed by applying coating which contains the ultra-fine metal oxide powder on PET film.
