    Binders for paints and varnishes - Determination of saponification value - Titrmetric method

    GB/T 6744-2008 "Bases for Paints and Varnishes - Determination of Saponification Value - Titrimetric Method" specifies a titrimetric method for determining the saponification value of bases used in paints and varnishes, applicable to various bases for colored and clear coatings. The method involves reflux saponification of the sample with a potassium hydroxide ethanol solution, followed by back-titration of the excess alkali with a standard hydrochloric acid solution to calculate the saponification value. The test requires instruments such as reflux apparatus, burettes, analytical balances, and constant-temperature water baths, providing technical support for the analysis of base composition and quality control of products.
