Abstract
1 Scope This document specifies a titrimetric method for determining the hydroxyl groups in resins and binders for paints and varnishes. This method is primarily suitable for neutral media. Acidic products provide higher values; neutral products provide, through neutralization of the acidic carbamates, lower values. For these products, preliminary tests are performed to ensure the applicability of the method.
