DryFilm RA-W is a dispersion of polytetrafluoroethylene (PTFE) at 20% solids in water. It can be applied to surfaces by dip coating, spraying, or brushing to form dry, thin films with a very low coefficient of friction. Films of DryFilm RA-W are chemically inert, nonmigrating, and stable in extreme temperatures. This makes them ideal for use as a mold release agent, dry film lubricant, and antifouling additive for coatings.

DryFilm RA-W is commonly used as a mold release agent in applications where the use of solvents is limited. Dry films of DryFilm RA-W will provide multiple releases between applications even when used with the most challenging materials, such as epoxy resins.

DryFilm RA-W can be added to water-based coatings and lubricants to improve lubricity, prevent fouling, and increase viscosity. It may also be used in waxes and polishes to increase lubrication.

When dry, DryFilm RA-W can be used on its own as a lubricant in applications that require smooth, repeated movements. Therefore, it is an ideal dry film lubricant for gears, bearings, electrical switches, and many other parts. It is often used as a dry lubricant in automotive applications where a traditional lubricant is too messy or laborious, such as automotive interior and assembly. DryFilm RA-W also provides an advantage as a dry film lubricant in resisting dirt and dust pickup that would otherwise occur on surfaces using wet lubricants.
