Adhesives — Determination of the solubility of water-soluble or alkali-soluble pressure-sensitive adhesives (ISO 25179:2018)
This document specifies a test method for the determination of the solubility of a water-solublepressure-sensitive adhesive in water or the solubility of an alkali-soluble pressure-sensitive adhesivein alkali by measuring the loss in mass of the adhesive when immersed in water or alkali. The solubilityof the adhesive is one of the key factors in assessing the possibility of recycling products to which labelsare fixed using a pressure-sensitive adhesive.
