High-temperature viscometer measures the flow behavior of powder coatings in the molten state.
This article introduces the use of a high-temperature viscometer to measure the flow behavior of powder coatings in their molten state. Powder coatings need to melt and flow before curing, a process that directly affects the smoothness and performance of the coating.
Selection of laboratory grinders is based on the fineness requirements of coatings, choosing between ball mills or sand mills.
The selection of a laboratory grinder should be based on the fineness requirements of the coating. A fineness greater than 50 microns indicates coarse dispersion, 10 to 50 microns is considered medium fineness, and less than 10 microns requires high fineness dispersion.
Mill Selection: Grinding Media and Material Fineness Targets
This article introduces how to select appropriate grinding media based on material characteristics and target fineness during the selection of a grinder.
How to Match the Selection of Fineness Gauge with Grinding Process Requirements
The fineness gauge is used to measure the particle dispersion of materials such as slurries and coatings, reflecting the particle size distribution through the depth of grooves on its surface.
Hall flowmeter measures the flowability of spray powder
This article introduces how a Hall flowmeter measures the flowability of spray powder. It uses a standard funnel to measure the time required for a certain mass of powder to flow out under gravity—the shorter the time, the better the flowability.
Tap density tester evaluates the accumulation characteristics of sprayed powder.
This article introduces how to use a tap density tester to evaluate the packing characteristics of spray powders. The tap density tester simulates vibration to densely pack the powder and measures the mass per unit volume, thereby obtaining the tap density.
Laser particle size analyzer measures the particle size distribution of spray powder.
Laser particle size analyzers measure the particle size distribution of sprayed powder based on the principle of light scattering, which is critical for coating uniformity and adhesion. During measurement, the powder must be dispersed in a suitable medium to avoid agglomeration, and tests should be repeated to ensure accuracy.
Operating Specifications and Result Interpretation of Paint Fineness Gauges
The fineness gauge is used to measure the dispersion of particles in paint. During operation, the sample should be applied to the groove under standard conditions, and a scraper is used to spread it evenly to form a wet film. The particle visibility is then observed under appropriate lighting, and the fineness value is read from the corresponding scale.
Sand Falling Test Apparatus for Measuring the Wear Resistance of Powder Coatings
The sand falling test instrument determines the wear resistance of powder coatings by simulating sand particle impact. During the test, abrasive material falls vertically from a specified height, continuously scouring the coating until the substrate is exposed. The wear resistance is evaluated based on the mass of abrasive material consumed.
Impact testing machine tests the impact resistance of powder coatings.
This article introduces the method of testing the impact resistance of powder coatings using an impact tester. The test simulates instantaneous impact through a falling weight or pendulum hammer, following ISO or ASTM standards.
Pendulum hardness tester measures the damping hardness of powder coatings.
This article introduces the method of testing the damping hardness of powder coatings using a pendulum hardness tester. The test is based on the principle of energy attenuation, where the hardness is reflected by the time it takes for the amplitude of the pendulum to decay as it swings on the coating surface, with a longer time indicating a harder coating.

This article introduces the method of determining the moisture content in powder coatings using a Karl Fischer moisture analyzer. Excessive moisture content in powder coatings can affect the quality of the coating, leading to issues such as bubbles. The Karl Fischer method measures moisture through the quantitative reaction of iodine and sulfur dioxide, which is divided into volumetric and coulometric methods.
