The coating agent of the present invention comprises a condensed polycyclic aromatic group or an organopolysiloxane having a group containing a condensed polycyclic aromatic group.

The electro-electronic device of the present invention is coated with a cured product of the coating agent.

A method of protecting a metal part of an electro-electronic device according to the present invention comprises the steps of: applying the coating material to a metal part of an electro-electronic device exposed to a corrosive substance; And curing the coating agent.

Effects of the Invention

On the other hand, if "a" exceeds the upper limit of the range described above, the transparency of the cured product is reduced. Also, if "b" exceeds the upper limit of the range described above, the stickiness of the cured product is produced. Further, if "c" is less than the lower limit of the above-described range, the refractive index of the cured product can be remarkably reduced.

The electro-electronic device of the present invention will be described in detail.

The electric-electronic appliance of the present invention is characterized in that the electric-electronic appliance is coated with a cured product of the coating agent. In particular, the metal part of the electro-electronic device is coated with a cured product of the coating agent. Electro-electronic devices of this type are exemplified by plasma displays, liquid crystal displays, organic electroluminescent displays and LEDs. The metal parts of this type of electro-electronic device are exemplified by electrodes, electrical circuitry of the circuit board and LED reflectors. Metal of this type of metal part, which is susceptible to corrosion by corrosive materials, is exemplified by silver, copper, aluminum, and alloys of these metals.

The method of the present invention for protecting the metal part of an electro-electronic device will be described in detail later.

The method of the present invention is a method for suppressing corrosion by applying a coating agent onto a metal portion of an electro-electronic device exposed to a corrosive substance and then curing the coating agent to suppress corrosion of the metal portion by the corrosive substance . The electro-electronic device is exemplified by a plasma display, a liquid crystal display, an organic electroluminescent display, and an LED. Metal parts of this type of electro-electronic device are exemplified by electrodes, electrical circuitry on the circuit board, and LED reflectors. Metal of this type of metal part, which is susceptible to corrosion by corrosive materials, is exemplified by silver, copper, aluminum, and alloys of these metals.

In addition, corrosive substances are exemplified by sulfur and sulfur-containing compounds. Examples of the sulfur-containing compound include hydrogen sulfide, sulfur dioxide gas, sulfuric acid mist, and mercaptan gas. The corrosive material is often present in the environment during the use or manufacture of electro-electronic devices and parts thereof. In addition, the corrosive material may arise from the internal component or material during use of the electro-electronic device.

According to the method of the present invention, the coating is first applied to a metal part of an electro-electronic device which is exposed to a corrosive substance. Prior to application of the coating, the current-conducting portion can be cleaned, if necessary. The coating method of the coating agent is not limited, and the coating method is exemplified by coating with a dispenser, coating with a scraper, and application with a brush.

According to the method of the present invention, there is no particular limitation on the thickness of the coating agent applied to the metal part. However, the thickness is preferably in the range of 100 μm to 5 mm. When the thickness of the coating agent applied to the metal part is less than the lower limit described above, the obtained cured product can not sufficiently inhibit the corrosion of the metal part by the corrosive substance. On the other hand, even if the upper limit of the above-mentioned range is exceeded, it does not show a remarkable improvement effect in the corrosion inhibition of the metal part due to the corrosive substance.

According to the method of the present invention, the coating is then cured. Although there are no particular restrictions on the curing conditions, room temperature curing is preferred to avoid heating the electro-electronic device. Of course, curing of the coating is promoted by heating. When the coating is cured at room temperature, the curing may take place preferably for a few minutes to about a week.

The coating was then applied to a thickness of 1 mm and the coated copper plate was heated in an oven at 150 캜 for 60 minutes to cure the coating and produce a test specimen. This specimen was inserted into a 450 mL volumetric hermetically sealable glass container containing 0.3 0.03 g sulfur. The system was allowed to stand at 80 DEG C for 51 hours, after which the specimen was removed from the glass container, the cured coating was removed using xylene, and the corrosion of the test specimen copper plate was observed. The degree of discoloration of the copper plates after the corrosion test was observed and evaluated as follows: o = no discoloration, DELTA = slightly discolored, and x = severe discoloration.

14.5 mg of coating was injected into the polyphthalamide (PPA) resin case of the LED and the assembly was cured at 150 캜 for 1 hour to produce an LED chip and an inner lead coated LED.

The LED was then inserted into a 450 mL volumetric hermetically sealed glass vessel containing 1.2 g of sulfur. The vessel was left at 80 DEG C for 116 hours or 428 hours and passed a current of 150 mA through the LED using a 2600 Sourcemeter (manufactured by Keithley Instruments Inc.). The light intensity of the LEDs was measured using an ISP 250 (250 mm) integrating sphere and a CAS-140 CT spectrometer (both manufactured by Instrument Systems GmbH). Also, the pre-test light emission intensity was regarded as 100% and compared. In addition, a microscope was used to observe the external appearance of the LED in the corrosion test.

After the dropwise addition, the mixture was heated at 50 DEG C for 30 minutes and stirred. Then, toluene and water were added, the mixture was stirred and the mixture was allowed to stand. Water washing was performed while repeatedly removing the lower layer. After confirming that the pH of the lower layer was 7, the upper layer (i.e., the toluene layer) was heated and distilled under vacuum to remove the low boiling point product. 43 g of a colorless transparent liquid were obtained (76.0% yield).
