Chemours DryFilm dispersions are used as dry film lubricants, release agents, and additives that improve lubricity and prevent the onset of fouling to coating formulations. DryFilm consists of white waxy particles of polytetrafluoroethylene dispersed in liquid that cures into a dry film lubricant with a low coefficient of friction. DryFilm is available in grades dispersed in water, isopropanol, or HFC 43-10 solvent. They are outstanding dry alternatives to lubricants like greases and oils where long-term friction reduction and lubrication, clean adherence to components, or cosmetic appearance is a top priority.
Common surfaces that DryFilm is applied to include metals, plastics, and rubber. It is applied to surfaces in a variety of methods, including dipping, wiping, brushing, or spraying. When applied to a surface, DryFilm forms a thin coating film with outstanding lubricity and thermal stability over a wide range of temperatures. DryFilm dispersions are non-flammable, chemically inert, non-staining, and resistant to corrosive chemicals.
As a release agent, DryFilm is commonly used in processes involving rubber and plastic part molds. Due to its chemical inertness, it is virtually unaffected by the mold or the material being molded. This allows release even with the most difficult materials.
When used as a dry film lubricant, DryFilm provides lasting lubrication for many applications that require smooth, repeated movements. DryFilm coatings will also provide abrasion resistance to lubricated parts, extending wear life.
DryFilm can also be added to liquid and semisolid formulations to enhance lubricant properties, promote thickening, and slow fouling. This makes it useful in coating applications such as paints, paper coatings, printing inks, waxes, and polishes for metals.
