LBT-T101 Coating Test on Tinplate and Aluminum-Iron Sheets

Coating testing on tinplate and aluminum‑steel sheets: For the performance evaluation of nearly all industrial coatings—covering adhesion, hardness, impact resistance, flexibility, bendability, and drying time—the coating film is typically applied to a tinplate substrate. The tin‑plating thickness, surface hardness, and surface treatment of the tinplate are the primary factors influencing test results.

LBT-T218 Automatic Coating Film Applicator

Automatic coating machines are used to prepare uniform, traceable coatings (manual coating often lacks consistency, particularly when performed by different operators, making sample comparisons difficult and even unreliable), and they offer excellent reproducibility. This is because the key factors influencing coating formation are the shear rate and the load applied to the applicator.

LBT-T219 Automatic Coating Film Applicator (Glass Platform)

Automatic coating machines are used to prepare uniform, traceable coatings (manual coating often lacks consistency, particularly between different operators, making sample comparisons difficult and even unreliable), and they offer excellent reproducibility.

LBT-T220 Automatic Coating Film Applicator (Economy Glass Platform)

An automatic coating machine is used to prepare uniform, traceable coatings (manual coating often lacks consistency, particularly when performed by different operators, which makes sample comparisons difficult and even unreliable), and it offers excellent reproducibility.

LBT-T227 Vertical Fully Automatic Coating Spray Booth

During coating performance testing, laboratory personnel must prepare a large number of uniformly consistent coated test panels. However, conventional manual spraying relies heavily on the operator’s experience and skill, making it difficult to ensure uniformity and consistency in the resulting coatings—particularly when applying coatings to large‑area panels—and potentially posing health risks to operators and environmental hazards if performed improperly.

LBT Intelligent Touch-Responsive Rheometer

Rotational viscometers are typically used to measure the viscosity—also referred to as apparent viscosity—of Newtonian or non-Newtonian fluids at specific rotational speeds and with particular rotor configurations. In industries dealing with polymeric materials such as coatings, inks, and adhesives, nearly all resins, emulsions, and finished products exhibit non-Newtonian behavior, displaying distinct rheological properties under varying shear rates that depend on both the rotational speed and the rotor geometry.

QAG Paint Flow-Resistance Tester

The relative sag resistance of a coating is determined by applying, with a doctor blade, strip‑shaped wet films of varying thicknesses onto glass test panels. The panels are then immediately positioned vertically so that the film exhibits a “thinner on top, thicker at the bottom” profile. After the film has dried, its sag resistance is assessed, expressed as the maximum film thickness in micrometers at which no sagging occurs.

QBB Coating Specific Gravity Cup

Applicable standards: GH6750 and ISO 2811. These standards are used to determine the density of paints and varnishes, where density is defined as the mass per unit volume at a specified temperature. Density cups are employed for quality control, as compositional deviations in coatings can result in inconsistent density readings.

QBJ Digital Display Cupping Tester

This standard is applicable to the evaluation of coatings—whether single-layer or multi‑coat systems—of paints, varnishes, and related products. Under the test methods specified in the standard, a compression‑indentation test is conducted; after the coating undergoes progressive deformation, its resistance to cracking or to delamination from the metal substrate is assessed, thereby determining whether the coating passes or fails.
