Drawdown Coating Machine

The film applicator with a drawdown bar uses an adjustable gap blade to uniformly coat a substrate at a constant speed, forming a homogeneous wet film. It is used in laboratories to simulate industrial coating processes and to test properties such as paint leveling and hiding power. It is suitable for quality control in industries such as inks and paints.
Selection
Select manual or automatic models based on sample viscosity, considering substrate thickness to match the adjustment range of the blade gap. Ensure compatibility with standard film thickness specifications and a user-friendly operation interface. Prioritize stainless steel corrosion-resistant materials to guarantee blade flatness. Pay attention to matching the equipment dimensions with the laboratory space.

Film Coating Machine vs. Spray Gun: The Impact of Different Coating Methods on Coating Performance Evaluation
This article compares two laboratory film preparation methods: the film applicator and the spray gun. The film applicator can produce coatings with uniform thickness and high reproducibility through blade coating, making it suitable for precise formulation studies. The spray gun simulates actual spraying, but the film thickness uniformity is poorer, and the surface may be rougher.
