The Automatic film applicator provides a reliable basis to apply coating films to test charts, panels or foils in a uniform and reproducible way in order to eliminate variations caused by human factors.
Variations in speed, pressure and direction of draw down cause irregularities. Other factors that may influence the result are the shear rate and the weight of the applicator. With the Automatic film applicator these variable factors are being stabilised. Over the complete surface the film thickness is even. Samples created with the Automatic film applicator are reproducible. It’s possible to produce a large number of identical laboratory precision draw downs in a short period of time.
The quality of the applied film is important for research on rheological properties of the applied media. To prepare samples for testing rheological properties, abrasion resistance, hiding power and gloss the Automatic film applicator is a must have. Multiple types of automatic film applicators are available for either glass/paper/metal substrates or foils.
Blok- and spiral applicators
All models can be used in combination with either standard block type film applicators such as bird/baker models, or spiral bar type film applicators (wire wound rod type) depending on the configuration chosen.
