FLUTEC LE12 and FLUTEC LE15 PERFLUOROCARBON COATING/IMPREGNATING SOLUTIONS ™

Description

Flutec LE12 and LE15 materials are solutions of a low molecular weight perfluorocarbon oligomer in a low boiling-point, volatile perfluorocarbon liquid.

Flutec LE12 and LE15 are clear, have very low surface energies and high contact-angles with water.

They are highly chemically-resistant to most liquids and solutions not containing fluorine atoms and will repel a variety of oils, lubricants and aqueous solutions of high and low pH.

Coatings remain flexible at low temperatures and melt between 60℃. and 80℃.

Uses

Items and surfaces coated or impregnated with FLUTEC LE12 and FLUTEC LE15 are simultaneously hydrophobic and oleophobic. This means that the solutions can be used for:-

• Protecting fully-assembled printed circuit boards and other electronics assemblies against condensed,
  atmospheric moisture.
  Areas:- External assemblies, intruder alarms, traffic systems, sea-going electronics, agricultural electronics.


• Impregnating / coating woven and non-woven fibres for protection against water and chemicals.
  Areas:- Paper for pet-food container, book protection, coating filter media.


• Coating applicator jets and nozzles to prevent clogging and to control shapes of droplets.
  Areas:- Ink-jet printers, adhesive applicators.


• Preventing migration of a large range of oils, lubricants, fluxes and inks into areas where they are not required.
  Areas:- Bearing-races, various containers (to ensure complete drainage), adhesive-joining “overspill”.


• Releasing resin mouldings from their moulds.
  Areas:- ‘Cold-cast1 resins, RTV-silicones.



Application Methods

Depending upon the specific use, ‘FLUTEC’ LE12 and ‘FLUTEC’ LE15 coatings can be applied by:

• Dipping
• Spraying.
• Brushing.
• Flood-Coating.
• Curtain-Coating.
• K-bar Coating.
• Hypodermic or other nozzle ‘spotting’.



Dipping, where practical, is preferred as equipment is available commercially which handles parts automatically and effectively recovers the solvent during drying of the coating.

Note: Where feasible, recovered solvent can be returned to F2 Chemicals for re-use.

Post-baking of dried films is not necessary.

Application equipment can be cleaned with any of the range of FLUTEC perfluorocarbon liquids.
