Automatic Film Applicator
An automatic film applicator improves the consistency of a drawdown. When more than one operator is drawing down the same coating or ink, the dry film appearance will vary because of different drawdown techniques. Drawdown speed and pressure on the applicator tool will impact the results. Film thickness, gloss, opacity, and color can vary with differing film applicator techniques. BYK-Gardner offers a large selection of automatic film applicators. The film applicators can accommodate virtually all drawdown chart sizes, applicator bars or wire-wound rods. Film applicators are available with vacuum plates or clip board designs.
Paint application onto a drawdown chart requires a highly precise coating applicator to achieve a consist dry paint film. Coating applicators can be a bar applicator or wire wound bar. BYK-Gardner offers a wide selection of bar applicators. The gap clearance and film width are important dimensions to consider when selecting a bar applicator. For wire wound rod applicators the wet film thickness, wire diameter, and film width should be considered. In North America wire wound bars are described as mayer rods; the single clearance bar applicators are described as a bird bar. There is large selection of multi-clearance coating applicators that can be used for many types of paint applications.
