Gap Drawdown Applicator

The gap applicator controls the wet film thickness by adjusting the gap between the blade and the substrate, and is used for coating and sample preparation of paints and inks. The principle involves the blade scraping across the substrate at a set gap to form a uniform wet film. It is applied in laboratory quality control, product development, and process validation.
Selection
When selecting a gap applicator, factors to consider include the type of substrate, the required wet film thickness range, material viscosity, and ease of operation. Match the blade material with the chemical compatibility of the sample being tested, ensure the gap adjustment accuracy meets testing requirements, and balance daily maintenance costs.
