Stainless Steel Bird Film Applicator®, 7.5" Length

For laying down wet films of materials in predetermined thicknesses. These precision wet film applicators are used in conjunction with paper charts, hiding power charts, plate glass or any other smooth flat surfaces. They are simple, accurate experimental or quality control devices that require no adjustments.

These applicators are fabricated from hardened and ground steel machined to a fine tolerance. 

The Wet Film Thickness is the nominal thickness of the coating when drawn down. The Wet Film Thickness is normally approximately one-half of the Cut, or actual gap clearance (depth) of the applicator. Example: An applicator with a .012" (12 mils) Cut Depth will lay down a Wet Film Thickness of .006" (6 mils). The Mark, or Wet Film Thickness is engraved on the end of the bar.

We can give no guarantee of the wet thickness that will be obtained. The wet thickness is dependent upon the solids and vehicle content of the wet material as well as other factors. Film thickness deposited may vary from 40% to 80% of the actual gate clearance of the applicator.

Be sure to order exact applicator desired. These applicators cannot be returned for credit or exchange. Keep in mind that unlike all other film applicators, Bird type blades are marked with the theoretical wet film thickness and that the actual cut or blade clearance is twice that of the wet film mark.
