example

[0039] The method of the present invention for protecting transparent non-metallic conductive parts will be described in detail using examples. The viscosities reported in the examples are values ​​at 25°C. Electrochemical corrosion testing of transparent non-metallic conductive parts was performed as follows.

[0040] [Electrochemical corrosion test of transparent non-metallic conductive parts]

[0041] Test specimens were prepared by coating a room temperature curable silicone rubber composition on a glass substrate to a thickness of 0.6mm, and then standing at 25°C / 50%RH for 1 week to cause curing, as figure 1 As shown, comb electrodes have been formed on the glass substrate using a 10 μm gap between the ITO conductive regions. The test sample was then kept at 60° C. / 95% RH for 96 hours while applying a voltage of 20 V between the electrodes of the test sample. After testing, the state of the transparent non-metallic conductive area was examined using a microscope to ...

Abstract

A method of protecting a transparent nonmetallic electroconductive part formed by, e.g., ITO, on a transparent substrate, e.g., a glass substrate, from electrochemical corrosion, is characterized by coating the transparent nonmetallic electroconductive part with a room-temperature-curable silicone rubber composition that contains from 1 weight-ppm to 30 weight% of a triazole compound, e.g., a 1,2,4-triazole compound or a benzotriazole compound; and thereafter curing the composition.

Description

technical field [0001] The present invention relates to a method of protecting transparent non-metallic conductive components formed of, for example, indium tin oxide (ITO) from galvanic corrosion. [0002] This application claims priority from Japanese Patent Application No. 2011-107848 filed May 13, 2011, the contents of which are incorporated herein by reference. Background technique [0003] Glass substrates with transparent non-metallic conductive parts such as electrodes or circuits formed of, for example, ITO are used in light-receiving display devices such as liquid crystal displays (LCDs) and electrochromic displays (ECDs) and light-emitting display devices such as electrochromic light-emitting display (ELD)). Transparent non-metallic conductive parts formed of, for example, ITO are generally prone to galvanic corrosion due to, for example, condensation, salts, etc. in environments with high humidity, environments where extreme temperature changes occur, and where ...
