Coating film stage

The coating applicator forms a uniform wet film on the substrate through mechanical scraping, used for testing properties such as coating hiding power and leveling. During operation, the sample is placed on the platform, and the thickness is controlled by adjusting the blade gap, making it suitable for laboratory quality control and product development processes.
Selection
When selecting, consider substrate compatibility; stainless steel surfaces offer corrosion resistance. Scraper accuracy affects film thickness uniformity and must meet testing standard requirements. Manual models are lower in cost, while automatic models provide better repeatability. Platform dimensions should accommodate common test sample specifications.
