Wire Bar and Formed Rods Coaters
The wire bar applicators and formed film applicators are made of corrosion-resistant stainless steel. A coating (paint or ink) is drawn down by a known thickness wire bar or form rod film applicator over a substrate (e.g., Black/White Test Chart, Glass or Wood Panel, etc.) The drawdown motion is achieved by gripping the two edges of the applicator or by using the Holder.
These applicators offer an economical means to ensure the uniform thickness of very thin films.
