The Differences Between Film Applicators

Testing the properties of products such as paints, varnishes, cosmetics, or glues for example; is an important part of their development. In order to test them, consistent and reproducible samples need to be made in order to undertake fair, accurate, and comparable tests. This is where film applicators and spiral bar coaters come in.

In this video, we’re going to show you each applicator, how they work, and the sort of applications they’re designed for. Unless otherwise stated, all of the applicators we are about to show you can either be used manually or with the Elcometer 4340 Automatic Film Applicator; and if you want to find out more about the Elcometer 4340, make sure you watch our separate video on that too.
