Pressure-sensitive adhesive double-coated sheet |
摘要 |
A pressure-sensitive adhesive double-coated sheet comprising a substrate, a pressure-sensitive adhesive layer (A) formed on one side of the substrate and a pressure-sensitive adhesive layer (B) formed on the other side of the substrate, wherein at least the pressure-sensitive adhesive layer (A) is formed with a pressure-sensitive adhesive comprising a butyl rubber as base material, and after the pressure-sensitive adhesive double-coated sheet is allowed to stand at 60° C. for five days while being placed between a moisture vapor-permeable waterproof sheet attached to the adhesive layer (A) and an aluminum plate attached to the adhesive layer (B), an expansion coefficient of the moisture vapor-permeable waterproof sheet is 0.5% or less. The pressure-sensitive adhesive double-coated sheet can allow the moisture vapor-permeable waterproof sheet to less expand over time when attached between the moisture vapor-permeable waterproof sheet and the adherend in a waterproof airtight structure of a construction.
