Square Preparation Device

The square applicator forms a uniform wet film on the substrate using a flat scraper, which is used for film thickness control and performance testing of coatings and inks. It is suitable for quality inspections in the laboratory, such as hiding power and adhesion tests.
Selection
When selecting, consider the compatibility between the substrate size and the applicator specifications, and determine the film thickness range based on the testing standards. The blade material must be corrosion-resistant, and ensure a stable coating speed during operation. Regularly clean the blade edge to prevent residues from affecting precision.

This article compares two commonly used tools in laboratory coating film preparation: the wire rod coater and the wet film applicator.
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.
