Press release date: Oct 02, 2014
“Manufacturers will use the results of testing as a means for product validation,” says Steven Brunner, application chemist, WPC Technologies. “For example, in the realm of anticorrosive pigment, WK46877 will serve as a means to estimate the amount of active portion in the pigment.” Brunner also notes that the test will be used to determine both the acceptable and detrimental levels of water for different types of pigments.
ASTM WK46877 is being developed by Subcommittee D01.31 on Pigment Specifications, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications. Interested parties are invited to join in the standards developing activities of D01.31. In addition to WK46877, the subcommittee is considering the development of a standard for pigment grind method.
