Scraper Film Applicator.

The drawdown Coater evenly applies coatings onto the substrate surface using a blade, forming a smooth coating layer. It is used in laboratories to simulate coating processes and test properties such as coating leveling and hiding power. It is suitable for the preparation and quality control of coatings on inks, paper, and plastic films.
Selection
When selecting, consider the substrate thickness and size to match the blade gap, choose the appropriate blade type based on the coating viscosity, incorporate temperature control functionality to accommodate different drying conditions, ensure ease of operation to meet daily experimental needs, and comprehensively evaluate maintenance costs and the convenience of component replacement.
