Liquid Coating Machine

The liquid Coater uniformly transfers liquid coating onto the substrate surface through rollers or blades, utilizing mechanical pressure to control the coating thickness. It is used in laboratories for preparing thin film samples and forming functional coatings on materials such as paper and plastic.
Selection
When selecting, consider the compatibility between the substrate type and width with the coating head specifications. Determine the roller gap or doctor blade angle based on the viscosity of the coating material. The temperature control system should be adjusted to match the solvent evaporation rate, and the operating speed must be coordinated with the drying device to prevent dripping or cracking.
