Document Type and Number:
Japanese Patent JP7340971
Kind Code:
B2
Abstract:
To provide an adhesive dust removal cleaner that is superior in an exterior appearance of an adhesive foaming layer.SOLUTION: An adhesive dust removal cleaner comprises an adhesive foaming layer obtained by foaming and reacting a foaming adhesive composition containing an acrylic polymer having a functional group reactable with an isocyanate group, a polyisocyanate compound, and a thermally expandable minute ball. The moisture content in the thermally expandable minute ball is 1.0 mass% or less, the moisture content that is found by precisely weighing the thermally expandable minute ball on a cell, introducing the thermally expandable minute ball and the cell into a heating vaporizing device, and collecting the moisture heated to 250°C in a dry nitrogen gas air flow and vaporized into the electrolyte in the titration cell, and also is found by the Karl-Fischer titration using a coulometric titration method.SELECTED DRAWING: None
