What Are the Core Characteristics and Advantages of Solvent Black 27?

As a synthetic organic dye, Solvent Black 27 exhibits multiple performance advantages that make it stand out in industrial applications. Its key characteristics include:

  • ‍Excellent solubility and broad solvent adaptability: It can dissolve in various organic solvents. Specific solubility data shows that its solubility reaches 60g/L in ethanol, 200g/L in methoxypropanol, 500g/L in methyl ethyl ketone, and 20g/L in toluene, which is suitable for different formulation requirements of processing systems.
  • Superior compatibility with resins: It has good miscibility with various industrial resins, which can avoid problems such as precipitation and delamination during the processing and application process, ensuring the stability of the final product.
  • Outstanding fastness performance: It has excellent acid resistance, alkali resistance and heat resistance. In heat resistance tests, it maintains stable performance at 150℃ for 30 minutes, 180℃ for 10 minutes and 200℃ for 1 minute (rated as Grade A) . Its light fastness reaches Grade 7, which can effectively resist color fading caused by light irradiation.
  • Vibrant and stable color: The dye presents a deep black color, and some products can show blue or red undertones according to different application needs. The color is bright and not easy to change, which can meet the aesthetic requirements of various products.
  • Compliance with safety standards: Its free chromium content meets international standards, and it complies with EU REACH and ROHS directives, as well as ISO 9001 and ISO 14001 certification requirements, which is conducive to application in global markets.‍

Application:

main used for Wood stains, Aluminium, Polyester & metals foils, Printing inks, Stationery inks, Glass, Plastic & Metal coatings, Leather & Plastic coloration/finishing etc.

What Are the Specific Industrial Applications of Solvent Black 27?

Benefiting from its comprehensive performance, Solvent Black 27 has been widely used in multiple industrial fields, covering coating, printing, coloring and other links. The main application scenarios include:

Printing inks:

It is an important colorant for printing inks, suitable for the production of various inks such as stationery inks and packaging printing inks, and can ensure clear patterns and long-lasting color.

Coating industry:

It is used in wood coatings, low-temperature baking paints, plastic coatings and metal coatings. For example, in wood staining, it can penetrate evenly into the wood texture and show a natural and deep color.

Metal and foil coloring:
