Feature of FluoroSurf |
|
* High performance for anti humid, water proof. * High resistant to lithium battery electrode * High resistant to acid gas and liquid * High insulation * Low dielectric constant * Non flammable liquid |
FLUOROSURF forms a thin film with high moisture-proof, salt water resistant, water-proof, acid-proof, lithium battery electrolyte resistant, and water/oil repellent properties and other protection functions. It has also high insulation resistance, low dielectric constant and other electric properties and is most appropriate for electronic component water-proofing, insulation protection and mounting printed circuit board moisture and water proof coating.
- ■In comparison with urethane and acrylic moisture-proof coating agents, its moisture-proof performance is four times higher and the thin film can sufficiently ensure moisture-proof effect. Weight increase by the coating film is restricted and therefore this is optimum for light-weight mobile and other devices.
- ■It is resistant to lithium battery electrolyte, protects the board against leakage of electrolyte and prevents firing.
- ■It provides high protection effect against acid gas, salt solution and corrosive solutions and prevents corrosion.
- ■It contains no silicone or other low-molecular compound and causes no contact failure of electric contact points after being coated.
- ■The agent dries at room temperature in 5 seconds to 30 minutes. Heating is not required.
- ■The non-flammable solvent does not catch fire and its toxicity is low. It is not subject to the PRTR Law (JAPAN)and Fire Defense Law(JAPAN).
- ■It’s viscosity is low easy to handle. It does not make the workplace dirty.
- ■The pot life is semi-permanent, without wastefulness.
- ■Soldering and other repair are possible.

■Film of only about 8 microns presents moisture-proofness of the same degree as that of conventional coating agent of 40 microns. When the film thickness is the same, moisture permeability is approximately 1/3 to 1/4 of that of conventional products.
【Salt Water Proofness (Insulation Breakdown)】
■This test result suggests the extra patience of our fluorine resin against insulation breakdown by salt water in comparison with general insulation urethane resin.

Test Method
- Coat the surface of each comb-shaped electrode wiring board of slit width of 200 microns respectively with various coating agents and leave them more than 1 hour to dry.
- 2. Drop 3-5ml of 5% salt water across slits and apply voltage of 18 to 19VDC through the wiring as shown in the left figure.
- While applying voltage, check the energization condition with an ammeter (measurement limit 0.01μA) until the salt water dries completely.
- If the leakage voltage exceeds 1000μA, stop the test immediately.
- ■Various specifications (resin concentration) of film thickness from 0.1 to 40 microns or more can be provided to meet versatile requirements.
- ■Coating liquid is non-flammable , as it is safe to use and not subject to the Fire Defense Law and PRTR Law.
- ■Soldering and other repair are possible.
- ■Blue coloring and fluorescent specifications are optionally available to be used to check the film. (When black light is irradiated, the film shines and can be recognized.)
