What are the characteristic advantages of Solvent Black 29?
Solvent Black 29 stands out in solvent dyes due to its comprehensive performance advantages, mainly reflected in the following aspects:
- Excellent solubility: It has high solubility in a variety of organic solvents. For example, the solubility in ethyl acetate, methyl isobutyl ketone and cyclohexanone can reach 500 g/L, and the solubility in ethanol is 400 g/L, which ensures uniform dyeing in different systems.
- Good thermal stability: The heat resistance can reach 200°C, which can maintain stable color without decomposition or discoloration in high-temperature processing scenarios such as plastic molding and low-temperature baking paints.
- Superior fastness: It exhibits excellent light fastness, with some high-quality products reaching grade 7, and general products also maintaining grade 4-6. At the same time, its acid and alkali resistance are both grade 5, which can resist the erosion of acidic and alkaline environments and maintain color stability.
- Strong compatibility: It has good compatibility with various resins, and can be well integrated with the matrix materials in coatings, inks and plastic products without affecting the physical properties of the base material.
- Stable coloring performance: The coloring intensity is controlled at 100±2%, which has strong coloring power and stable color shade, ensuring the consistency of batch production colors.
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 applications of Solvent Black 29?
Relying on its excellent performance, Solvent Black 29 is widely used in multiple industrial fields, mainly covering the following categories:
- Printing ink field: It is the core colorant for flexographic and gravure inks, suitable for printing on various substrates such as paper, plastic, printed aluminum foil, metallized polyester film, mobile phone packaging materials and glassine paper.
