Blade-Type Film Applicator

The blade-type film applicator applies a liquid sample onto a substrate surface by scraping it with an adjustable gap blade, forming a uniform wet film. It is used in laboratories to simulate the scraping process and test the leveling, hiding power, and film thickness consistency of coatings and inks. It is suitable for evaluating the coating performance on materials such as paper and plastic films.
Selection
When selecting, consider the viscosity range of the sample and match it with the blade gap. The substrate thickness should be flat. Stainless steel blades are corrosion-resistant. Manual models are suitable for occasional use, while electric models ensure uniform coating speed. Pay attention to the anti-slip design of the base and the blade parallelism adjustment function.
