韩国采购需求：功能性纳米粉末、成品薄膜、分散液、功能性中间膜、功能性母料

We're on the hunt for either a coating that can be applied to glass or a glass product that comes pre-coated. We're especially interested in materials that can reflect infrared radiation, have high thermal resistance (up to around 400 °C), and maintain optical transparency in the visible spectrum. If you have any products, coatings, or materials that fit this description, please let us know. We're looking forward to your response and hope to explore potential options together. Thanks!
