WEST CONSHOHOCKEN, PA - ASTM said two proposed standards currently under consideration will provide a "definitive chemistry" to evaluate the performance of coatings applied to coil galvanized steel.
The standards are designed to be "precise and quantitative, to give a particular number to tell what their adhesion or corrosion performance will be," said Duane Fudge, a chemical engineer with Betz Dearborn who prepared the draft standards with other members of ASTM Subcommittee D01.53 on Coil Coated Metal. Subcommittee members represent the steel, chemical and coatings industries.
