Zusammenfassung:A roof liner capable of adhering to a roof panel, the liner comprising: (a) a roof membrane having a first major surface and a second major surface; and (b) a pressure sensitive adhesive disposed on the first major surface of the roofing membrane and comprising: (i) at least one of butyl rubber or polyisobutylene; (ii) a first liquid plasticizer, preferably polybutylene; and (iii) a tackifier, wherein the adhesive has a Tg of up to about 100 C. The adhesive provides high bond strength and excellent long-term thermal aging resistance, weather resistance, and good low temperature characteristics while providing moisture resistant seams. A method for manufacturing the roof liner includes applying the adhesive to the film and then applying a release liner on the adhesive layer. A method for using the roof liner includes removing the release liner and then adhering the liner to the roof panel by contacting the first with the roof panel. 一种能够粘附至屋顶板上的屋顶衬料,该衬料包含:(a)具有第一主表面和第二主表面的屋顶膜;和(b)压敏粘合剂,该压敏粘合剂布置在该屋顶膜的该第一主表面上并且包
