Wet Film Coating Applicator

Wet Film Coating Applicators provide one of the most accurate and reproducible methods of applying a coating to a flat surface for further evaluation. Since most physical properties are dependent on applied thickness, it is of paramount importance that not only must the thickness of a coating be reproducible, but also the correct value of thickness must be known. On average, applicants with the most common contour will apply a wet coating thickness, just one-half of the physical clearance between the blade and the surface receiving the coating.

There is some variation in this ratio depending on the physical properties of the coating and the rate of “drawdown” of the coating on the surface by the applicator. The careful operator will determine this ratio for his particular material and operation conditions.
