Standard Practice for Evaluating the Water Wash-Off Resistance of Traffic Paints using a Water Faucet

Importancia y uso:

5.1 After waterborne traffic paints are applied to a road, airstrip, or parking lot pavement, it is important that the paint films be sufficiently hardened, coalesced, or cured so they will not be removed by rain. This practice can be used to determine the relative performance of binders and other components within traffic paint for their effect on the water-wash off resistance of the coating. Some key elements of the coating that may affect water-wash-off performance are the quality and type of latex binder, the dry time of the coating (often conducted by Test Method D711), pigment volume concentration (PVC), and the relative water sensitivity of additives (for example, pigment dispersants, and surfactants) in the coating.
