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 [mu]m. 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.

Description

technical field [0001] The present invention relates to a moisture-proof insulating paint having a high shielding property against visible light by coating and drying the coating film. More specifically, it relates to a moisture-proof insulating paint characterized in that the total light transmittance of a coating film produced by using two or more dyes and being able to be coated and dried is 5% or less at a film thickness of 100 μm. Furthermore, the present invention relates to a moisture-proof insulating material obtained by applying and drying the moisture-proof insulating paint. Furthermore, the present invention relates to an electronic component insulated by the moisture-proof insulating material. Background technique [0002] Electrical equipment tends to become smaller, lighter, and multifunctional every year. The mounted circuit boards that can control electrical equipment and are mounted on various electrical equipment are designed to prevent damage from moistur...
