Usage

Description

PYRROLE BLUE is a synthetic dye characterized by its vibrant greenish-blue color. It is slightly soluble in cold water and becomes more soluble in hot water, displaying a greenish-blue hue. PYRROLE BLUE is not soluble in alcohol and exhibits a unique reaction to strong sulfuric acid, turning red light brown, and upon dilution, it forms a blue precipitate. When mixed with a sodium hydroxide solution, the dye solution turns violet black, accompanied by precipitation.

Uses

Used in Textile Industry:
PYRROLE BLUE is used as a dye for coloring fabrics, providing a range of greenish-blue shades. Its properties make it suitable for various textile applications, including clothing, home textiles, and decorative items.
Used in Paint and Coating Industry:
PYRROLE BLUE is used as a pigment in the paint and coating industry, offering a bright and long-lasting color. Its light fastness and resistance to fading make it an ideal choice for outdoor applications and products that require a durable finish.
Used in Plastics and Polymer Industry:
PYRROLE BLUE is used as a colorant in the plastics and polymer industry, adding a distinctive greenish-blue hue to various plastic products, such as toys, packaging materials, and consumer goods.
Standard:
The performance of PYRROLE BLUE is measured using the ISO and AATCC standards, which evaluate its acid resistance, alkali resistance, light fastness, soaping, water fading, and stain fading properties.
