GB/T 31412-2015 stipulates the titration method for the determination of the hydroxyl value of lacquer base for Paints and varnish. The standard specifies the scope of application, explains the determination principle in detail, specifies the equipment, reagent materials, sample prepative, titration steps, etc., and gives the calculation and result representation method of the hydroxyl value. It provides a unified standard for the scientific and accurate determination of the hydroxyl value of lacquer base, which is helpful for evaluating the performance of lacquer base and controlling the mass of Paints and varnish products.
