DryFilm RA Dispersion is a 15% solids dispersion of specialty sized polytetrafluoroethylene (PTFE) in HFC 43-10 solvent. It can be used as a mold release agent, dry lubricant and coating additive.
DryFilm RA dispersion is based on extremely stable fluoropolymer technology and forms coatings with outstanding anti-stick properties. The low coefficient provided by DryFilm RA makes it an ideal dry lubricant for applications where repeated smooth movement is necessary like electrical switches, bearings, and hardware. DryFilm RA can also be added to liquid and semi-solid formulations like greases and coatings to increase lubricity, adjust viscosity, and prevent fouling. Additionally, the stability and low coeffcient of friction of DryFilm RA makes it an ideal mold release agent for molding of plastics and rubber. It will not interact with mold or molded parts and it provides longer lasting mold release performance than silicones.
