Japanese Patent JP2018080213
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive composition that has excellent adhesiveness and adheres to glass at low-temperature environment, and has a low moisture vapor permeability, and therefore inhibits moisture absorption into an element when used as a sealing material in an electronic device, and can maintain stable quality for a long time, and provide an adhesive sheet.SOLUTION: An adhesive composition contains a plurality of polyisobutylenes (A) having different weight average molecular weights, and polybutene (B) that is liquid at 23°C. Relative to the whole composition, the content of (A) is 70-95 wt.% and the content of (B) is 5-30 wt.%. An adhesive sheet comprises the adhesive composition.SELECTED DRAWING: Figure 7
