Heated Coating Tester

The heated coating tester uses an electric heating device to heat the substrate, applying liquid materials uniformly with a blade or roller under controlled temperatures. It is used to simulate the coating process of hot-melt adhesives and coatings on paper or films, testing coating thickness, uniformity, and thermal stability. It is commonly applied in ink suitability testing and the development of composite processes for packaging materials.
Selection
When selecting, ensure the material viscosity range is matched, confirm temperature control accuracy within ±1℃, and verify that the heating plate size covers the width of commonly used substrates. Pay attention to the micrometer-level precision of the blade gap adjustment and prioritize corrosion-resistant material for the chamber. Validate the heating rate of the equipment for compatibility with the laboratory power supply, and ensure a third-party calibration interface is retained.
