Fluorine is a unique substance that reacts with all elements to create a variety of fluorine compounds. Once it forms a compound, it becomes chemically stable and exhibits excellent properties including heat, chemical, and corrosion resistance, water and oil repellency, and lubricity. Capitalizing on these properties, it is used in products ranging from household goods, such as irons and frying pans, to automobile fuel hoses, exterior coatings for buildings, and refrigerants used in air conditioners. Its applications are wide and diverse. Daikin fluorine-based products span the world with unique technology that plays an important role in global industries and supports society as indispensable material. There are also expectations for it as a material that contributes to conserving energy and resources.
