Surface Profile
Surface profile
Surface profile, also addressed as surface roughness is another parameter that plays an important role in the surface prep process. Besides clean surface a certain roughness required to assure proper adhesion of the paint or coating to the surface.
By creating a rough surface with “peaks and valleys” one is more or less increasing the total surface area thus creating a larger bonding area for the paint to stick. Paint specifications often require a certain surface roughness or anchor profile. In order to guarantee the performance of coating system. A surface profiles which is too low may cause adhesion problems. However a surface profile which is too coarse could effect that the primer coating is not covering the “peaks” of the anchor pattern which may lead to premature corrosion or other problems with the intermediate or top coat. A coarse surface also leads to an increase of the paint consumption.
Creating a specified surface roughness is not an easy job. The profile is determined by the size, type and hardiness of the abrasive being used, the air pressure, and by the distance and angle of the nozzle to the surface.
