The high-efficiency film-coating technique is an essential innovation in the modern chemical industry, significantly reducing reliance on operator skills while boosting overall efficiency and precision. Our adjustable film applicator provides a versatile solution for achieving varying coating thicknesses from 0-3500μm, with an impressive accuracy of up to 1μm, making it an indispensable tool for precise coating applications. This device is ideal for applying wet films of a specified thickness, allowing users to evaluate the covering power of a specimen, assess color quality, or create sample plates across diverse fields. It caters to numerous applications in coatings, printing, paints, cosmetics, pharmaceuticals, adhesives, batteries, and scientific research. Specifications include a durable aluminum alloy frame and scraper, a coating thickness range of 0-3500μm, effective coating widths of 50mm, 55mm, 100mm, 150mm, 200mm, or 300mm, and a precision level of 2μm. Package includes one adjustable film applicator and one storage case for convenient transport and protection of the device. Please note that the differential head may require occasional adjustments to ensure accuracy, and the relationship between wet film thickness and scraper clearance varies based on material properties, viscosity, and application techniques. After use, it is important to clean the instrument thoroughly with an appropriate solvent (not included) to maintain functionality and longevity.
