    Resin finishing agent―Determination total formaldehyde content、free formaldehyde content and methylol formadehyde contend

    GB/T 5543-2006 "Resin Finishing Agents—Determination of Total Formaldehyde Content, Free Formaldehyde Content, and Hydroxymethyl Formaldehyde Content" specifies the test methods for determining three formaldehyde-related contents in resin finishing agents, applicable to various types of resin finishing agents. The acetylacetone spectrophotometric method is employed, where the content is quantitatively calculated by measuring the absorbance after a color development reaction. The test requires instruments such as a spectrophotometer, constant-temperature water bath, analytical balance, and volumetric flasks, providing critical data for evaluating the environmental performance and safety control of resin finishing agents.
