Wet Film Gap Preparator

A wet film thickness gauge applies a coating onto a substrate using a metal bar or ring to scrape, forming a wet film layer of fixed thickness. It is used to simulate the state of coating application and to test properties such as the leveling and hiding power of the coating. It is commonly used in laboratory quality control of coatings and during the formulation development process.
Selection
When selecting, consider the compatibility of the substrate size with the coating width, ensuring the coating thickness range covers the testing requirements. The stainless steel material offers corrosion resistance, and the operating handle should be non-slip. Verify the uniformity of the film thickness after coating and the ease of cleaning and maintenance. Choose the appropriate gap accuracy based on the viscosity of the coating.

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.
