Architectural Paints and Stains
A proposed new ASTM International test method will combine existing in-house methods for dirt pick-up resistance for architectural paints and stains in an effort to standardize testing for dirt repellency throughout the industry.
The proposed standard, WK38233, Test Method for Dirt Pick-Up Resistance for the Films of Architectural Paints and Stains, is currently being developed by Subcommittee D01.42 on Architectural Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications.
According to Amanda Andrews, chemist, Wacker Chemical Corporation, and a D01.42 member, the proposed standard will focus on:
Andrews notes that Primary users of WK38233, once approved, will be coating suppliers and manufacturers.
Andrews invites all interested parties to participate in the ongoing development of WK38233.
"We are particularly interested in participation from those who already have in-house dirt pick up test methods with formulated dirt," says Andrews. "We are also looking for participation from anyone who has interest in appropriate accelerated methods such as artificial UV and water conditioning."
In addition to its work on WK38233, D01.42 is currently working on a revision to D4446, Test Method for Anti-Swelling Effectiveness of Water-Repellent Formulations and Differential Swelling of Untreated Wood When Exposed to Liquid Water Environments, as well as another proposed new standard, WK32143, Test Method for Visual Assessment of Water Beading on Horizontal Coatings.
