The Automatic film applicator provides a reliable basis to apply coating films to test charts (max. size 515 x 300 mm / 20.28 x 11.81 in), 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.
Block- 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.
Each Automatic Film Applicator ‘Standard’ is equiped with the Triple I ® Navigation Tool. The Triple I stands for Intelligent Illumination Interface. This unique navigation tool guides the operator through the interface of TQC Sheen lab-machines. At each step of the operating menu the interface detects which buttons are active and indicates these by means of an illuminated red centre. This results in a very intuitive operating system which is enhanced with information on the machine’s display.
The Automatic Film Applicator Standard with perforated heated vacuum bed has a built-in heating mat which allows the temperature of the table to be elevated up to +100°C above ambient temperature. The powerful heating device guarantees an even distribution of the temperature over the entire vacuum plate. Temperature is set and controlled by means of the Triple I ® Navigation tool
