Manual Coating Application Rod

The manual coating bar is a commonly used tool in laboratories. It controls the coating thickness through grooves on the bar, allowing for the uniform application of liquid samples onto substrate surfaces. It is used for thickness testing and quality control of coatings and inks, offering simple operation and suitability for small-scale experiments or on-site rapid testing.
Selection
When selecting a manual coating rod, consider the substrate type, the required wet film thickness range, and the sample viscosity. Match the groove depth to the target thickness, opt for durable stainless steel material, and ensure the width is suitable for common substrate sizes. Pay attention to the rod's flatness and the clarity of its scale to ensure coating uniformity.
