Application of Laser Particle Size Analyzer in Coatings

Coatings are widely used in architecture, industry, and home furnishings, imparting decorative aesthetics, corrosion resistance, rust prevention, weather resistance, and scrub resistance. Specialty coatings also offer special features such as fire resistance, antibacterial properties, and antistatic properties, making them key materials that combine protection and functionality.

Testing the particle size distribution of coatings is a crucial quality control and analysis method. Its impact on product performance runs through the entire process of production, storage, application and even the final coating film.

1. Determines coating stability

Too large particle size or too widely distributed can easily cause pigments and fillers to settle and clump during storage, shortening their shelf life. Fine and uniform particle size, on the other hand, creates a stable suspension.

2. Affect the final appearance and optical properties of the coating

Particle size affects how light scatters and is a key factor in determining hiding power, gloss, and color. Improper particle size can lead to defects such as reduced hiding power, uneven gloss, color blurring, or floating color.

3. Closely related to construction performance

Particle size affects the rheological properties of the coating (such as viscosity, leveling and anti-sagging), which in turn affects the difficulty of spraying, brushing and other operations and the final film-forming effect.

Testing the particle size distribution of coatings is the basis for ensuring their stability, optimizing construction performance, and achieving the desired coating appearance. Laser particle size analyzers are crucial to improving the competitiveness and production efficiency of coating products by quickly and accurately quantifying particle size and its distribution.

This time, Winner2309A is recommended to test the particle size distribution of coatings for customers. As a new generation of intelligent wet and dry laser particle size analyzers, the winner2309 represents a significant leap forward in appearance, measurement range, intelligence, and test intervals. Its measurement range is 0.01-3500μm. It is mainly used to test the particle size of metal powder, non-metal powder, other powders and emulsions, etc.

Measuring instrument information is as follows:
