Abstract
A pressure-sensitive adhesive composition includes 100 parts by mass of a rubber component containing 40 to 93 mass % of a butyl rubber and 7 to 60 mass % of a polyisobutylene and 82 to 128 parts by mass of a softener having a kinetic viscosity at 40° C. of 100 to 9000 mm2/s.
Claims7
A pressure-sensitive adhesive composition comprising:
- 100 parts by mass of a rubber component containing 40 to 93 mass % of a butyl rubber and 7 to 60 mass % of a polyisobutylene and
- 82 to 128 parts by mass of a softener having a kinetic viscosity at 40° C. of 100 to 9000 mm2/s.
A pressure-sensitive adhesive sheet comprising:
- a pressure-sensitive adhesive layer formed from a pressure-sensitive adhesive composition containing
- 100 parts by mass of a rubber component containing 40 to 93 mass % of a butyl rubber and 7 to 60 mass % of a polyisobutylene and
- 82 to 128 parts by mass of a softener having a kinetic viscosity at 40° C. of 100 to 9000 mm2/s.
A moisture-permeable waterproof pressure-sensitive adhesive sheet comprising:
- a moisture-permeable waterproof sheet and
- a pressure-sensitive adhesive sheet laminated on the moisture-permeable waterproof sheet, wherein
- the pressure-sensitive adhesive sheet includes a pressure-sensitive adhesive layer formed from a pressure-sensitive adhesive composition containing
- 100 parts by mass of a rubber component containing 40 to 93 mass % of a butyl rubber and 7 to 60 mass % of a polyisobutylene and
- 82 to 128 parts by mass of a softener having a kinetic viscosity at 40° C. of 100 to 9000 mm2/s.
