Coating Preparation Tester

The coating preparation tester uses a blade or roller to uniformly apply the coating onto the substrate, simulating the actual coating process. It is used to test coating thickness and uniformity, and is suitable for laboratory coating process research on materials such as paper and film.
Selection
When selecting, consider the coating method to be consistent with production, substrate size matching machine specifications, coating thickness range meeting testing needs, ease of operation, corrosion-resistant equipment materials, reasonable maintenance costs, and reference to actual user feedback.
