By necessity, paint used for roadway applications needs to dry quickly. Some multi-component traffic paints cure in less than 10 minutes, some much faster. Because of this speed of curing, these traffic paints and other types of fast-cure (less than 10 minutes) multi-component paints cannot be tested for volatile content using procedures outlined in the ASTM International standard typically used for this purpose, ASTM D2369, Test Method for Volatile Content of Coatings.
To accommodate fast-cure paints, Subcommittee D01.21 on Chemical Analysis of Paints and Paint Materials is now developing a proposed new standard, WK22148, Test Method for Volatile Content of Fast Cure Multi-Component Paints.
Dave Salman, environmental engineer, U.S. Environmental Protection Agency and chair of the ASTM D01.21.24B task group that is developing WK22148, says that all interested parties are invited to join in the development of the proposed new standard. In addition, Salman says the task group is seeking sample materials and volunteers to participate in interlaboratory testing.
Subcommittee D01.21 is part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
For technical Information, contact Dave Salman, U.S. Environmental Protection Agency, Research Triangle Park, N.C. (phone: 919-541-0859; salman.dave@epa.gov). Committee D01 meets June 21-23 in Norfolk, Va.
ASTM International welcomes and encourages participation in the development of its standards. ASTM’s open consensus process, using advanced Internet-based standards development tools, ensures worldwide access for all interested individuals.
