Four-Sided Wet Film Preparator

The four-sided wet film applicator uses four different gap blades to create four distinct thicknesses of wet film on a substrate in a single pass. It is used for coating liquid materials such as paints and inks to test properties like leveling and hiding power. It is suitable for quickly preparing comparative samples in the laboratory.
Selection
Select the blade gap range based on the viscosity of the test material, considering the compatibility of the substrate material and size with the applicator width. Stainless steel material is corrosion-resistant. During operation, ensure the substrate remains flat and the coating speed is uniform. Clean and store properly after use to avoid damage to the blade gap.

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.
