Bird-type coater

The bird-type applicator transfers coating onto the substrate surface by rolling a metal rod, forming a uniform wet film. It is used in laboratories to simulate the blade coating process and test properties such as the leveling and hiding power of coatings. It is suitable for evaluating the coating quality of inks, paper, and plastic films.
Selection
When selecting, consider the substrate flatness and size compatibility with the coating width. Choose a coating rod with an appropriate wire diameter based on the viscosity of the coating. The coating thickness is determined by the groove depth of the rod. Stainless steel material is required for corrosion resistance, and manual operation should ensure a consistent pushing speed to guarantee coating uniformity.

The importance of maintaining a constant speed when using a wet film applicator for coating.
When using a wet film applicator, maintaining a constant speed during the scraping process is crucial for coating uniformity. The scraping speed directly affects the wet film thickness, and fluctuations in speed can lead to defects such as streaks and uneven thickness, compromising the repeatability and accuracy of experimental results.
The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
