Wet Film Four-Sided Applicator

The wet film four-sided applicator uses four grooves of different depths to draw down coatings onto a substrate, creating four wet films of varying thicknesses. It is used for quickly preparing test coatings to evaluate properties such as leveling and hiding power. It is applied in quality control and formulation development within the coatings and ink industries.
Selection
When selecting a four-sided wet film applicator, consider the type and size of the substrate, and ensure the coating thickness range covers the testing requirements. The material should be corrosion-resistant stainless steel, with an ergonomic handle for ease of operation. The specifications must align with industry standards to ensure measurement accuracy and operational convenience.

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. The thickness value is then obtained by the operator reading the scale of the first tooth that becomes coated with the varnish.
