Binders for paints and varnishes - Determination of glass transition temperature

GB/T 27816-2011 "Binders for paints and varnishes—Determination of glass transition temperature" specifies the method for determining the glass transition temperature of binders used in paints, varnishes, and powder coatings by differential scanning calorimetry (DSC). The principle involves eliminating the thermal history of the sample and using a differential scanning calorimeter to record the temperature transition curve to determine the characteristic temperature value. The testing requires an analytical balance with an accuracy of 0.1 mg, a paint film applicator, DSC-specific sample pans, and a high-purity nitrogen purging device, strictly following the heating and cooling procedures to provide accurate data support for the performance evaluation of binders.
