Zirconium is used as an anti-corrosive finishing/surface treatment on metal substrates. If the coating of zirconium is too thin, then the sought-for metal property will not be achieved. Similarly, applying too thick a coat means that treatment material is wasted and so is money. Therefore, ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications has developed a…, ASTM Committee D01 Next Meeting:, Jan. 30-Feb. 1, 2011, January Committee Week, Baltimore, Md., Technical Contact:, Christelle Petiot, Oxford Instruments Analytical, High Wycombe, Buckinghamshire, United Kingdom; christelle.petiot@oxinst.com, ASTM Staff Contact:, Jeffrey Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8685/Sept2010

ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications, has approved two new standards that cover architectural coating touch-up properties and ink stainblocking of paint systems. Both new standards are under the jurisdiction of Subcommittee D01.42 on Architectural Coatings., Touch-Up Properties, When a home is being constructed, paints are subjected to a wide variety of drying conditions, which can lead to differences in appearance between the original coat and subsequent touch-up areas after the paint has fully cured. A new standard, ASTM D7489 , Practice for Evaluating Touch-Up Properties of Architectural Coatings Under Various Environmental Conditions, covers variations in color,…, Ink Stainblocking, Paint companies and raw material suppliers will be able to use a new ASTM standard to assess the capability of architectural coatings for blocking ink stains from bleeding through to a topcoat. The standard, ASTM D7514 , Test Method for Evaluating Ink Stainblocking of Architectural Paint Systems by Visual Assessment, represents a compilation and synthesis of methods that are currently being used…

Traffic paint plays an important role in maintaining the safety of roads. Subcommittee D01.44 on Traffic Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications, is currently working on two proposed new standards covering the sampling of waterborne traffic paint and glass bead gradation measurement., WATERBORNE TRAFFIC PAINT, Ensuring that traffic paint taken from the field is tested properly in laboratories is a concern of paint suppliers as well as private testing laboratories, Department of Transportation labs, DOT striping crews and striping contractors. A proposed new ASTM standard, ASTM WK22312 , Practice for Drum and Tote Sampling of Waterborne Traffic Paint, addresses laboratory sampling issues. According to…, GRADATION OF GLASS BEADS, Glass beads added to traffic paint during manufacturing are necessary to ensure paint retroreflectivity, especially at night. A proposed new standard, ASTM WK23758 , Test Method for Measuring Gradation of Glass Beads Using a Flowing Stream Digital Image Analyzer, will be useful in the production and quality control of glass beads. “Digital camera technology combined with high speed computers has…
