Compliance & Certification | Technical Parameters “Low VOC” has become a standard selling point for coatings and colorants. However, most users have only a vague understanding of how VOC is actually measured, calculated, and what environmental labels specifically require. Different standards, different sampling methods, and different calculation bases can yield vastly different VOC values for […]

Compliance & Certification | Technical Application-Oriented Industrial coatings and food packaging represent two scenarios with the most divergent compliance requirements for colorants. The former focuses on domestic standards like the China Environmental Labeling (Ten Circle Mark) and VOC limits, while the latter adheres to food contact regulations such as FDA and EC 1935/2004. A single […]

When selecting and applying water-based colorants, a set of core parameters is unavoidable: solids content, particle size, viscosity, and pH. They are interconnected and mutually constraining, collectively determining tinting strength, stability, compatibility, and application performance. Viewing any parameter in isolation leads to pitfalls—for example, pursuing high solids content only to end up with high viscosity, […]

Publication: Coating Technology & Abstracts | Technical Parameters Introduction Among the many core technical parameters of colorants, Particle Size Distribution (PSD) is the most telling microscopic indicator of dispersion process capability and product consistency. It acts as an invisible ruler, fundamentally determining tinting strength, transparency, gloss, and even storage stability from the very start. Many […]

On the path of innovation in printing materials, Zhejiang Namei Material Technology Co., Ltd. has never stopped exploring. Its meticulously researched and developed UT series – UV Pigment Dispersion (Inkjet) has become a highly regarded focus in the industry with its unique advantages and excellent performance. The nano-scale particle size and narrow distribution range of […]
