Laboratory Coating Rod Applicator

The laboratory scraper wire rod Coater controls the coating thickness through a metal wire rod, with the scraper evenly spreading the liquid sample. It is used for the standardized coating preparation of substrates such as paper and film, supporting subsequent process tests such as drying and curing.
Selection
When selecting, consider matching the substrate size to the coating width, aligning the wire rod specifications with the required wet film thickness, and choosing a blade material suitable for the sample characteristics. The operation method should be determined based on experimental frequency, opting for manual or automatic, and additional functions should be configured according to actual testing needs.
