Multi-sided Wet Film Coater

The multi-sided wet film applicator uses a metal rod with grooves of different depths to scrape and form a wet film layer of specific thickness on the substrate surface. It is used in laboratories to simulate printing and coating application processes, and to evaluate properties such as material leveling and hiding power.
Selection
When selecting, consider matching the substrate type and size to the coating width, aligning the required wet film thickness with the groove depth, determining the groove structure based on material viscosity, and focusing on handle design and cleaning methods for operational convenience.

Selection of wet film thickness gauge range and accuracy requirements for comb teeth spacing.
When selecting a wet film thickness gauges, the key considerations are the measurement range and the accuracy of the comb teeth spacing. The range should cover the coating thickness with a slight margin to avoid being too small for measurement or too large, which could reduce resolution.
Wet film thickness gauge measures the wet film thickness of varnish.
The wet film thickness gauge is a mechanical tool used to measure the thickness of liquid varnish coatings. It operates by rolling the gauge so that the tips of its teeth contact the substrate and leave marks.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process.
