Title:
MOISTURE-PROOF INSULATIVE COATING WITH VISIBLE LIGHT-BLOCKING PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2012/124737
Kind Code:
A1
Abstract:
Provided is a moisture-proof insulative coating for electronic parts which exhibits superior electrical insulation reliability and visible light-shielding properties. The moisture-proofing insulating coating comprises a thermoplastic elastomer, two or more kinds of dyes and a solvent, and the total light transmittance of a coated film produced by coating and drying said coating is 5% or less when the film thickness is 100 μm. The thermoplastic elastomer is preferably a styrene thermoplastic elastomer such as a styrene-butadiene-styrene block copolymer elastomer. At least one of the dyes is preferably an anthraquinone dye. The dye content is preferably 0.1 - 10 parts by mass with respect to 100 parts by mass of the thermoplastic elastomer. The moisture-proofing insulating coating preferably also comprises a tackifier such as a petroleum resin tackifier.
