Sample Coating Rod

The drawdown bar uses a smooth metal strip to apply a coating onto a substrate, forming a uniform wet film for the rapid preparation of test samples in the laboratory. During operation, the thickness and width are controlled to facilitate the observation of coating properties such as hiding power and leveling. It is suitable for quality control in industries such as inks and pigments.
