COOLING-AND-PEELING TYPE SELF-ADHESIVE COMPOSITION, COOLING-AND-PEELING TYPE SELF-ADHESIVE SHEET, AND MANUFACTURING METHOD OF 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.
