Standard Practice for Evaluating the Water Wash-Off Resistance of Traffic Paints using a Water Faucet
Also Known As:
ASTM D7377-09 (R2018) addresses the need to assess the ability of traffic paint films to resist being washed off by rain after application. The practice involves subjecting freshly applied traffic paint films to simulated heavy rain conditions using a water faucet in a controlled laboratory environment.
The standard highlights the importance of ensuring that the paint films have hardened, coalesced, or cured sufficiently to prevent their removal by rain. It identifies several factors that may impact the water-wash-off performance of the coating, including the quality and type of latex binder, dry time of the coating (measured by Test Method D711), pigment volume concentration (PVC), and the relative water sensitivity of additives such as pigment dispersants and surfactants.
