Spray-type Applicator

A spray Coater atomizes the coating material using air pressure or hydraulic pressure and uniformly sprays it onto the substrate surface to form a thin layer. It is used in laboratories to simulate industrial spraying processes, test coating coverage and drying effects, and is suitable for coating preparation on paper, plastic, and metal surfaces.
Selection
When selecting a spray-type Coater, it is essential to consider the compatibility between the coating viscosity and the atomization method. The substrate size determines the movement range of the spray head, while control precision affects the uniformity of the coating. The equipment material must be resistant to solvent corrosion, and the operating interface should be simple and easy to use for adjusting spraying parameters.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
