Water/Oil Repellent Properties

The film of fluoride resin coating repels water and oil strongly and prevents diffusion and attachment of oil or water. This is useful for various objects.

*Click each function to go to detailed description

Fluoride resin film formed on the surface repels water and oil strongly. It constitutes a barrier against grease (prevents its bleeding), prevents water and oil from diffusing or attaching and protects surfaces from fouling. The fluoride resin film provides diversified merits.

  • Just coat the agent to acquire strong water/oil repellent properties. Soaking or bleeding of liquid or fouling can be prevented by the functional coating.
  • Non-flammable, low-toxicity solvent can be safely handled. This is not subject to the Fire Defense Law, Industrial Safety and Health Law and PRTR Law.
  • The agent dries at room temperature. You may select the drying time between 5 seconds and 30 minutes.
  • Mounted components or plastic parts are not affected.
  • Film thickness can be adjusted depending on the purpose. You may select resin concentration.
  • You may select non-flammable solvent according to your purposes (contact us for details).

  • The agent can be diluted to about 10 to 20 times with water or ethyl alcohol when using.
  • Film thickness can be adjusted by changing the dilution ratio.
  • The agent dries at ambient temperature, forms water and oil repellent film of fluorine resin and repels water and oil. This film may not soluble to water.
  • Antifouling function and bleeding grease/resin blocking function can be obtained.
  • The agent can be easily coated by dipping or using a brush.
  • As the resin concentration can be selected, film thickness can be adjusted according  to purposes.
  • No surfactant is used and environmental contamination needs not be worried.
