Title
(EN) ADHESIVE TREATMENT LIQUID, AND METHOD FOR TREATING ADHESIVE
(FR) LIQUIDE DE TRAITEMENT D’ADHÉSIF, ET PROCÉDÉ DE TRAITEMENT D’ADHÉSIF
(JA) 粘着剤処理液、および粘着剤処理方法
Abstract
(EN) Provided are: an adhesive treatment liquid capable of easily removing various types of adhesives; and a method which is for treating adhesive and by which various types of adhesives are easily removed. For example, when an adhesive tape including a substrate and an adhesive is to be treated, provided are an adhesive treatment liquid capable of easily detaching various types of adhesives from a substrate, and a method which is for treating adhesive and detaches an adhesive from various types of adhesives. An adhesive treatment liquid according to an embodiment of the present invention is a treatment liquid for an adhesive, wherein the adhesive treatment liquid includes a liquid having a Hansen solubility parameter value of at most 31 and an alkaline compound, and the concentration of the alkaline compound is 0.001-20 wt%.
(FR) La présente invention concerne : un liquide de traitement d’adhésif capable de retirer facilement divers types d’adhésifs ; et un procédé destiné à traiter les adhésifs et par lequel divers types d’adhésifs sont facilement retirés. Par exemple, lorsqu’une bande adhésive comprenant un substrat et qu’un adhésif doit être traité, la présente invention concerne un liquide de traitement d’adhésif capable de détacher facilement divers types d’adhésifs d’un substrat, et un procédé qui sert à traiter l’adhésif et qui détache un adhésif de divers types d’adhésifs. Un liquide de traitement d’adhésif selon un mode de réalisation de la présente invention est un liquide de traitement d’un adhésif, le liquide de traitement d’adhésif comprenant un liquide ayant une valeur de paramètre de solubilité de Hansen d’au plus 31 et un composé alcalin, et la concentration du composé alcalin est comprise entre 0,001 et 20 % en pds.
(JA) 様々な種類の粘着剤を容易に除去できる粘着剤処理液、および、様々な種類の粘着剤を容易に除去する粘着剤処理方法を提供する。例えば、基材と粘着剤を含む粘着テープを処理対象とした場合には、基材と様々な種類の粘着剤を容易に分離することができる粘着剤処理液、および、基材と様々な種類の粘着剤を容易に分離する粘着剤処理方法を提供する。 本発明の実施形態による粘着剤処理液は、粘着剤の処理液であって、ハンセン溶解度パラメータ値が31以下である液体とアルカリ化合物を含み、アルカリ化合物の濃度が0.001重量%~20重量%である。
