The Determination of Metallic Zinc Content of Inorganic and Organic Zinc-Rich Primers by Differential Scanning Calorimetry

摘要

Although several methods exist for determining the metallic zinc content of the zinc dust pigment in inorganic and organic zinc rich primers, no generally recognized method exists for the analysis of the metallic zinc content in the dried films of such coatings. This paper demonstrates a rapid and precise method, based on differential scanning calorimetry, for making this determination.
