S 9.1.3 Color shade differences
The appearance and color shade of virtually every paint finish undergo changes, depending on its age, amount of wear-and-tear and maintenance.
This is immediately apparent from the obligatory color shade comparison using a spray plate. Consequently, a correct repair-painting procedure may also
include a color shade comparison through re-tinting or touching up ( -> S 4.2.6 "Painting procedure information").
If you decide to re-tint the repair paint, the mixture formula of the color shade in question serves as a tinting aid.
The application method also changes the appearance and color shade of a paint finish. This means that the appearance and color shade of a paint finish
depend on:
-
The nozzle settings of the spray gun and the spray pressure (-> S 9.1.3.1)
-
The amount of thinner used and the spray viscosity (-> S 9.1.3.2)
-
The spray method used (-> S 9.1.3.3)
-
The distance between the spray gun and the object to be painted (-> S 9.1.3.4)
S 9.1.3.1 Dependency on the nozzle settings of the spray gun and the spray pressure
Criteria that affect the appearance and color shade of a paint finish:
-
The color shade is lighter if a fine spray is used. A fine spray is produced using a small nozzle setting and high spray pressure.
S 9.1.3.2 Dependency on the amount of thinner used and the spray viscosity
Criteria that affect the appearance and color shade of a paint finish:
-
The silver effect can generally be made more brilliant with thinner that evaporates faster than with thinner that evaporates more slowly.
-
The higher the spray viscosity, the more likely you are to have cloud formation.
