粘合剂.水溶性或碱溶性压敏粘合剂溶解度的测定

[中文适用范围]： 本文件规定了通过测量粘合剂浸入水中时的质量损失来测定水溶性压敏粘合剂在水中的溶解度或碱溶性压敏粘合剂在碱中的溶解度的试验方法或碱。 粘合剂的溶解度是评估使用压敏粘合剂固定标签的产品回收可能性的关键因素之一。 [外文原描述]： This document specifies a test method for the determination of the solubility of a water-soluble pressure-sensitive adhesive in water or the solubility of an alkali-soluble pressure-sensitive adhesive in alkali by measuring the loss in mass of the adhesive when immersed in water or alkali. The solubility of the adhesive is one of the key factors in assessing the possibility of recycling products to which labels are fixed using a pressure-sensitive adhesive.
