BONDERITE® S-FN 309 (also known as Emralon 309) is a high-performance solution of concentrated polytetrafluoroethylene (PTFE) particles in an IPA-based solvent carrier that dries onto surfaces to form a robust low-friction coating.  BONDERITE® S-FN 309 exhibits excellent surface adhesion on a wide variety of substrate types including wood, fabric, metal, plastic, glass & rubber.  BONDERITE® S-FN 309 allows for reduced surface friction and wear, leading to extended equipment life and a reduction in preventative or emergency maintenance cycles. 

BONDERITE® S-FN 309 is a powerful dry-film solution for long term protection in a wide range of applications, including but not limited to:
 
Aerosol Lubricant Formulating Component
Sealed Systems
Action-Parts or Mechanisms in Pianos
Tool Lubrication & Protection
Solenoid Plungers
Window Guides or Slides
Moving Parts (wood, plastic, rubber, metal, fabric)

Great Suspension Stability
Very Fine Particle Size
White, Non-Staining Color
Excellent Compatibility with Chemicals or Propellants
Great Lubrication Performance
Low Delivered Friction
