Standard Practice for Determining the Dry Fall (Fog) Properties of Protective Coatings

Importancia y uso:

5.1 Attachment of overspray particles to vehicles and other surfaces not intended to be coated can result in property damage and insurance claims. Dry fall coatings are formulated such that overspray particles dry as they move through the air, and before they land on horizontal surfaces. These particles can then be brushed off, vacuumed or washed from the surfaces with no damage. This practice can be used to evaluate the dry fall properties of coatings prior to large scale use. The practice can also be used to evaluate whether the coating(s) possess the same dry fall properties when the fallout collects on surfaces with an elevated temperature.
