Automatic Film Applicators

The Film Applicators offer a reliable and repeatable method for applying samples of paints, inks, varnishes, adhesives and other materials that require a defined film thickness evenly spread over flat surfaces.

We are currently running special offers on the SH1137 Film Applicator (Valid until 30th June 2017).

Consistency of application

Inconsistency arises when Film Applicators are used by hand to apply coating materials. Variations occur that impact on
the consistency of film thickness, colour and covering power. The advantage of the Automatic Film Applications is that they always offer the same conditions of application such as speed of application (this can be varied to achieve optimum results), applied pressure to the sample and flatness. These conditions combined with a set Bar Applicator gap and geometry offer best practice to obtain perfectly reproducible samples.

Scope of testing

The coating properties that can be determined when using the Automatic Film Applicators and associated Applicator Bars include: wettability, wet film thickness, dry film thickness, levelling, sagging, opacity and colour.
