Thick Adhesive Coater

The thick film applicator evenly spreads high-viscosity coatings onto substrates using a blade or rod structure to form a thicker coating layer. It is used in laboratories to simulate industrial coating processes, test the leveling, hiding power, and drying characteristics of coatings, and is suitable for the preparation of thick films such as inks and adhesives.
Selection
When selecting, consider the matching of the coating thickness range with the sample viscosity, ensure the blade material is corrosion-resistant, and verify that the substrate width is suitable for the experimental sample. The operation methods are divided into manual and mechanical, chosen based on precision requirements. Pay attention to the control of coating speed and ease of cleaning, and evaluate the impact of environmental temperature and humidity.

The heating film coater applies thick-film resistor paste onto the ceramic substrate.
The heating coating machine is used to apply thick film resistor paste on ceramic substrates. It reduces the viscosity of the paste through a heating platform and ensures uniform coating in conjunction with the coating head.
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.
