Title:
HOT-MELT ADHESION COMPOSITION, HOT-MELT ADHESIVE SHEET AND ADHESION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/111507
Kind Code:
A1
Abstract:
The invention provides a hot-melt adhesive composition comprising a hot-melt adhesive, a ferromagnetic body, and a foaming agent that foams when heated, the hot-melt adhesive composition characterized in having a surface magnetism of 20 mT or greater, a surface magnetism after heating for adhesion of 5 mT or less, and a percentage volume change on heating for adhesion of 110 to 400%. By means of a hot-melt adhesive sheet obtained by forming the hot-melt adhesive composition into a sheet, superior strength is realized by heating and sufficient temporary anchoring force by magnetism is seen initially, but there is a sufficient reduction in magnetism after heating such that it is possible to prevent surface irregularities attributed to lines of magnetism after heating.
