Product Introduction The coating tester is a high-precision, multifunctional, automated
sample preparation platform meticulously developed by LONROY, based
on rigorous laboratory standards and diverse material application
requirements. By employing precise closed-loop control over three
core parameters—coating speed, coating pressure, and substrate
flatness—this equipment elevates the laboratory coating process
from an experience-based "manual art" to a quantifiable,
reproducible "exact science." Its highly versatile design meets the
coating preparation needs of sectors ranging from traditional
chemicals to cutting-edge new materials, providing reliable,
indispensable samples for R&D and quality control. Applications New Energy Materials: Lithium-ion battery cathode slurries, anode
slurries, conductive slurries, and sodium-ion slurries. Traditional
& Specialty Chemicals: Coatings, inks, paints, UV adhesives,
pressure-sensitive adhesives, and hot-melt adhesives. Cutting-edge
Functional Materials: Perovskite precursors, nanomaterials,
catalyst coatings, and gels. Compatible Coating Substrates: Metal
Foils: Aluminum foil, copper foil. Flexible Films: Separators
(non-woven fabrics), PET. Core Technical Advantages: Eliminating
instability at the source Precision Linear Coating System Driven by a high-performance motor, the system enables stepless
speed regulation within the 1–100 mm/s range (expandable). With a
speed stability error of less than 1%, it ensures uniform linear
coating, perfectly simulating various production processes. Quantifiable Pressure Control System Featuring a proprietary (or "precision") pneumatic/mechanical
pressure application system, it enables digital setting and precise
feedback of coating pressure. Users can configure quantitative
parameters based on slurry rheology and film thickness
requirements, completely eliminating batch-to-batch variations
caused by relying on "manual feel" for pressure control. Ultra-flat Reference Plane System The work surface is constructed from high-grade mold-quality
stainless steel. Precision-ground and specially treated, it offers
exceptional flatness (≤0.002 mm) as well as superior corrosion and
deformation resistance, providing the ultimate foundation for
achieving uniform, consistent coatings. 2. Coating Method Parameters 2.1 Adjustable Doctor Blade 2.1.1 Thickness: 10–3000 µm (other

straightness errors of the doctor blade do not equate to wet film
coating errors, as coating viscosity and particle size also affect
coating precision during the process. Additionally, coating flow
characteristics and the wet-to-dry film formation ratio can
mitigate machine-induced errors.
