Application of Laser Particle Size Analyzer in Coatings

Coatings have evolved from simple "paint" into an indispensable engineering material, widely used in construction, industry, home furnishings, and special fields. It provides decoration and protection for building walls and floors, gives automobiles and home appliances an aesthetically pleasing appearance and corrosion resistance, and is used for corrosion protection of ships and bridges. In addition, functional coatings can achieve special effects such as fire resistance, conductivity, stain resistance, and antibacterial properties, making them important engineering materials that combine aesthetics, protection, and functionality.

The particle size distribution of coatings has a profound impact on their performance and applications.

1. Fine and evenly distributed particles can form a dense and smooth paint film, significantly improving the coating's gloss, hiding power, and feel, as well as enhancing its weather resistance and corrosion resistance.

2. Excessively wide distribution or coarse particles can lead to a rough surface, dull luster, and may cause problems such as settlement stratification and construction difficulties.

3. Particle size directly regulates the rheological properties of coatings, affecting their storage stability and application leveling properties. Therefore, precise control of particle size is key to optimizing the final appearance and overall performance of coatings.

Laser particle size analyzers are a key tool in coating research and quality control. They accurately measure the particle size distribution of resin, pigment, and filler particles in coatings, and this data is directly related to the stability, workability, and final film formation of the coating. By optimizing the particle size distribution, the gloss, hiding power, and durability of the coating can be effectively improved, while preventing defects such as settling and floating color. This is an important guarantee for achieving precise control of coating performance.

This time, Winner2308A is recommended to test the particle size distribution of coatings. Winner2308A wet and dry integrated laser particle size analyzer can switch between dry and wet dispersion with one click. Both liquid coatings and powder coatings can be tested. Various technical difficulties of the wet and dry integrated machine have been solved. It is well received by institutions and universities. Its testing range is 0.01-2000μm (wet) and 0.1-2000μm (dry). It features a dual-optical design with a wide testing range and fully automatic intelligent operation.
