W. CONSHOHOCKEN, PA – 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 stain blocking of paint systems. Both new standards are under the jurisdiction of Subcommittee D01.42 on Architectural Coatings.
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, gloss and sheen that impact the touch-up capacity of a paint.
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 Stain Blocking of Architectural Paint Systems by Visual Assessment, represents a compilation and synthesis of methods that are currently being used to evaluate stain blocking. The standard will help companies evaluate and differentiate between different resin technologies used in the manufacture of stain-blocking primers.
