High color power green light yellow pigment yellow 138

The series of pigment yellow 138 on the market up to 84 kinds of dosage forms, fully meet the needs of different industries and application scenarios. This pigment is known for its unique strong green light yellow, vivid and full color, when mixed with blue pigments (such as the classic copper phthalocyanine CuPc), can be blended with various levels of green tones, providing a rich choice of colors for artistic creation and industrial design. Its low surface area (compared to Hansa Yellow 10G's 8m²/g, pigment Yellow 138 has a lower specific surface area) makes the pigment more evenly dispersed in applications, reducing energy consumption and costs. At the same time, its high hiding power makes it possible to achieve excellent coverage even on light-colored substrates, and excellent light fastness ensures long-term color retention.

The molecular weight of pigment yellow 138 is precisely controlled at 395.2, which ensures the stability of the pigment's performance. Its hue or color light is precisely defined as bright green and yellow, providing a clear color guide for visual design. The density reaches 1.6g/cm³, and the bulk density is between 10.4-13.7lb/gal, which is easy to store and transport. The melting point ranges from 235 ° C to 254 ° C (different batches may vary slightly), ensuring stability and controllability of the pigment during processing. The average particle size is controlled between 0.48 and 0.57μm, and the particle shape is rod-like, which helps to improve the dispersion and gloss of the pigment in the paint and ink.

The specific surface area ranges from 6 to 12m²/g, providing a good pigment and substrate bonding force. The pH value is measured from 6.0 to 7.5 in a 10% slurry, ensuring the compatibility of the pigment in a variety of systems. The oil absorption is between 22-60g/100g, and the fluidity and viscosity of the pigment can be adjusted to adapt to different application needs. The shading is translucent, providing designers with more layers of color expression.

Green light yellow powder pigment yellow 138, bright and pure color, melting point up to 258 ° C, at 150 ° C for 20 minutes can remain stable, showing excellent heat resistance. When heated, it can be dissolved in ethanol, acetone and other organic solvents, which is easy to process and adjust. It is yellow when encountering concentrated sulfuric acid, but the color remains unchanged in concentrated nitric acid, concentrated hydrochloric acid and dilute sodium hydroxide, showing its good chemical stability and corrosion resistance. Good sun and heat resistance, even in harsh environmental conditions can keep the color bright and durable.
