Sample Coating Applicator

The drawdown Coater uses a blade to evenly spread coating on a substrate surface, forming a wet film of standard thickness. It is used in laboratories to simulate the coating process and evaluate the leveling, hiding power, and color effects of coatings. It is suitable for sample preparation and quality control of inks, paper, and plastic films.
Selection
When selecting, consider the blade material's corrosion resistance, the coating width matching the sample size, and the thickness adjustment range covering common film thicknesses. Pay attention to the stability of substrate clamping, ease of operation, and difficulty of cleaning and maintenance. Determine the blade type based on the viscosity of commonly used coatings, and select heating or vacuum platform functions according to experimental requirements.
