Thin Film Fluorine Coat "FC-180"

Thin Film Fluorine Coat FC-180

We have newly developed contamination-free surface coating “FC-180”, which can withstand repeated exposure to cleaning chemicals, such as highly concentrated alkaline solutions.

Repelling alcohol in a needle

A metal surface usually has an affinity with water, alcohol, oil, and other liquids. If the surface becomes wet with alcohol, for example, liquid drops will spread on the surface. “FC-180” coating forms a fluorine coat on the metal surface which improves its water repellency and prevents a deposition of adhesives on a needle and micro channel. FC-180; the transparent fluorine coat with as thin as less than one μm thickness, having water- and oil repellency; requires no changes in dimension of the current products.
Please try this newly developed fluorine coating.

Features of "FC-180"

  • ・The coating has submicron (<1 μm) in thickness, giving minimal dimensional effects.
  • ・Uniform coating is also available on the inner surface of a pipe with an inner diameter of about 0.3 mm.
  • ・The firing process at a low temperature to form the coating layer gives no adverse effects on the works such as nozzles.
  • ・A transparent antifouling coating with high adhesiveness, and high hardness can be formed.
  • ・The high chemical resistance of this coating allows your products to be repeatedly used

Evaluation of chemical resistance

We have evaluated the durability against repeated cleaning by accelerated test using a highly concentrated alkaline solution.

【Evaluation method】
 ①The specimen was immersed in 10% NaClOaq solution with ultra-sonic wave for accelerating the test effect, and the surface was observed at every 30 minutes.
 ②The result values of fluorine coat thickness are calibrated with the elemental analysis measured by an electronic microscope.
【Evaluation result】
 No degradation is observed after the 90 minutes dipping test in 10% NaClOaq solution.

Thin Film Fluorine Coat FC-180 on the SUS304 plate

The photo shows the surface of a sample after immersed 60 minutes in 10% NaClOaq solution. No degradation of water- and oil- repellent is observed.

No thickness change of the "FC-180" coating is observed, after the plate is immersed in 10% NaClOaq solution for 90 minutes.

Effects of thin film fluorine Coat "FC-180"
Demonstration moving pictures (on the SUS304 plate)

Spraying isopropyl alcohol.

(left) ↓No coating
(right) ↓Coated "FC-180"

The right half coated with “FC-180” shows that the sprayed alcohol does not stick to the surface like to the left side, making the alcohol droplets round shape. This shows the excellent draining property of the coating.

Immersed in the milk

(right) ↓Coated "FC-180"

The right half coated with “FC-180” shows that the milk does not stick to the surface like to the left side, making the milk separate from the surface quicker. This shows the excellent draining property of the coating.

FC-180 coating allows you to easily remove the residual liquid inside a nozzle by air blowing due to its water- and oil repellency, resulting improvement of the cleaning workability and reducing of contaminations inside a needle.
