Laboratory Sample Coater

The laboratory drawdown machine uses a blade to create a uniform wet film on a substrate, which is used for testing the hiding power and leveling properties of coatings and inks. The Coater applies a measured amount of sample onto paper or film using rollers or blades, simulating industrial production conditions. Both are used for quality inspection, formula development, and process parameter verification.
Selection
Select manual or automatic models based on sample viscosity, consider matching the coating gap with substrate thickness, ensure compatibility with different coating methods such as wire rods and blades, guarantee temperature control accuracy meets material curing requirements, and ensure the operation interface is simple and easy to maintain.
