Title (EN) METHOD FOR APPLICATION OF COMPOSITE PRESSURE SENSITIVE ADHESIVE
(FR) PROCEDE D"APPLICATION D"UN ADHESIF COMPOSITE SENSIBLE A LA PRESSION
Abstract: front page image
(EN)A composite pressure sensitive adhesive construction contains a central release liner (20), a layer of an adhesive (30, 35) on each side thereof, and optionally, an exterior release liner (40, 45) on at least one of the adhesive layers. The central release liner and the exterior release liner contain release coatings (21, 22, 41, 46) on surfaces thereof which contact the adhesive layer. The pressure sensitive adhesive construction may be utilized in sealing pipe insulating jackets (60) wherein the exterior release liners are removed and the adhesive construction is applied to the opposite longitudinal ends or sides (67, 68) of the insulating jacket cover. The insulating jacket may then be stored until utilized whereupon the central release liner (20) is removed, the jacket inserted about the pipe, and a sealing connection then made by pressing the two exposed adhesive layers together.
(FR)Une structure d"adhesif composite a pression comprend un support central de detachement (20), une couche d"un adhesif (30, 35) de chaque cote du support, et eventuellement, un support de detachement exterieur (40, 45) sur au moins l"une des couches adhesives. Le support central de detachement et le support exterieur de detachement possedent des revetements de detachement (21, 22, 41, 46) sur leur surface qui sont en contact avec la couche adhesive. La structure adhesive sensible a la pression peut etre utilisee pour l"etancheite des chemises isolantes (60) de tuyaux ou les supports de detachement exterieurs sont enleves et la structure adhesive est appliquee sur les extremites ou cotes longitudinaux opposes (67, 68) de la chemise isolante. La chemise isolante peut alors etre stockee jusqu"a son utilisation, moment auquel le support de detachement central (20) est enleve, la chemise est ajustee autour du tuyau, et une liaison d"etancheite peut alors etre realisee en pressant les deux couches adhesives exposees l"une contre l"autre.
