Appearance:Earthy yellow powder. Soluble in water. Good high temperature stability.



Application:It is suitable for one bath dyeing of polyester viscose and polyester cotton blended fabrics, especially for one bath one-step dyeing, silk dyeing and paper dyeing. The dyes commonly used for ink jet printing have the following requirements: high purity (HPLC purity is at least more than 99%), extremely low salt content and heavy metal elements, low viscosity, high surface tension, good solvent compatibility and storage stability. In particular, dye purity is one of the main indexes affecting the performance of ink jet ink.

Quality guarantee period: 24 months.

Packing: 25kgs iron drum.

Storage:Store in a cool and ventilated room and prevent moisture and heat.
