Cooling removable pressure-sensitive adhesive composition, the cooling-peelable pressure-sensitive adhesive sheet, and a method of manufacturing an electronic component using the same

摘要

PROBLEM TO BE SOLVED: To provide a cooling-and-peeling type self-adhesive composition capable of being used in a wide temperature range, excellent in releasability after used in a temperature range of 80-100°C, and usable for a wide variety of applications.;SOLUTION: The cooling-and-peeling type self-adhesive composition contains a self-adhesive polymer as an available component, has an initial self-adhesive force of ≤0.2 N/25 mm in a temperature region of 0-30°C (an ordinary temperature region), has a self-adhesive force of ≥1 N/25 mm (self-adhesive force at high temperatures) in a temperature region of 80-100°C (a high-temperature region), and has a self-adhesive force (self-adhesive force after cooling) of ≤0.2 N/25 mm when cooled down to the ordinary temperature region from the high temperature region.;COPYRIGHT: (C)2005,JPO&NCIPI
