    Wet Film Thickness Gauge

    Overview Products Knowledge Standards Terms
    The wet film thickness gauge measures the thickness of coatings before they are cured through mechanical contact. The principle involves a disk or roller contacting the surface of the wet film, with thickness calculated by converting geometric displacement. It is used for on-site monitoring of coating application quality to ensure the coating thickness meets requirements. It is commonly applied in fields such as shipbuilding and steel structure coating.
    Selection
    When selecting a wet film thickness gauge, consider a measurement range that covers the coating thickness, with a mechanical structure suitable for rough surfaces. Check the clarity of the scale for easy reading, and opt for stainless steel material for corrosion resistance. Choose between roller or disc types based on coating characteristics, and compare standard specifications to confirm accuracy. Consider portability and environmental adaptability.

    The fineness gauge is used to measure the dispersion of particles in paint.

    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. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
