Pearlescent pigments, as the name suggests, give the coating a pearly luster. They are not just pigments, but provide a special decorative effect that cannot be matched by traditional pigments. The determination of pearlescent luster is a key step in ensuring that these pigments achieve the desired effect. The following is a detailed analysis and interpretation.

Step 1 Define

Pearlescent gloss refers to the pearlescent effect of reflecting light when light hits the coating due to the specific structure and particle shape in the pearlescent pigment. This gloss includes brightness, fullness, color saturation and many other aspects, giving a sense of depth and three-dimensional, enhance the decorative paint.

2. The importance of pearlescent luster

In coatings, cosmetics, printing and other fields, the application of pearlescent pigments has become more and more popular. Not only do they add a high-end, luxurious feel to the product, they can also change the visual effect of the product and make it more appealing. Therefore, the accurate determination of pearlescent gloss to ensure that it achieves the desired effect is crucial to the quality and market acceptance of the product.

3. How to determine pearlescent luster?

Specific samples can be made using specific materials and instruments, such as black and white cardboard, resin and paint film coater. By comparing the sample with the reference sample and observing the reflected light characteristics under specific lighting conditions, the pearlescent gloss level can be evaluated.

This observation is usually performed under scattered daylight or standard light sources to ensure accuracy. The difference in brightness and pearlescent effect of the coating can be observed respectively on black and white substrates.

4. Pearlescent gloss type and rating

There are various types of pearlescent gloss, including bright pearlescent, soft pearlescent, silky pearlescent, shimmering pearlescent and strong shimmering pearlescent. These gloss effects are visually different and provide a different visual experience for the product.

In order to better distinguish and evaluate the pearlescent luster, the degree of difference is divided into: approximate, slight, slightly, more four levels. At the same time, these ratings also take into account the brightness and darkness of the coating.

5. The importance of standardization

In order to ensure the accuracy and consistency of the measurement of pearlescent luster, specific standards need to be referred to. Chemical industry standards and enterprise standards provide clear guidance and reference for determination, ensuring consistency across different production batches and products.

For example, the two standards “Mica pearlescent pigments” and “pearlescent pigments” provide detailed methods and requirements for the determination of pearlescent luster, ensuring the accuracy and reliability of the determination.

Step 6 Summarize

Pearlescent pigments give a unique decorative effect to coatings and other products, and the determination of pearlescent gloss ensures the consistency and high quality of this effect. Through accurate determination and evaluation, consumers can be provided with higher quality products to meet their decorative and aesthetic needs.
