Environment-friendly metal complex water-based dyes are divided into three series, with complete colors. Pure water-based dyes only need to be dissolved and dispersed directly with water. Metal complex water-based powder dyes can be dissolved in solvents such as ethylene glycol ether/methanol/ethylene glycol/dimethylformamide, or can be dissolved by adding water and solvent. They have excellent solubility, good compatibility with various resins, bright colors, good acid resistance, alkali resistance and heat resistance, and no free heavy metals. According to the needs of different industry products to provide powder and liquid two categories, and for different requirements of supply, liquid dye (color essence) easy to use, no dust pollution.

Metal Complex Dye

Precautions

1. Before use, according to their respective process requirements, experiments should be carried out to understand its solubility in this solvent. Attention should be paid to the selection of the best solvent and dissolution method, otherwise it will result in many precipitates, low dye content, different dyeing depths and other adverse consequences.

2. After the dye is dissolved, trace substances will be analyzed after long-term storage. Therefore, a 300-400 filter screen should be applied to filter the dye to prevent the precipitated substances from entering the next process.

3. When dissolving, add the amount of solvent to the dissolver, then add the dye in batches, stir for a few minutes after adding, wait for 1-2 hours, stir again, and settle still. If the dye is not completely dissolved, add a proper amount of solvent to extract the usable dye and pour out the remaining useless impurities.

4, product packaging powder packaging: 5kg, 25kg/paper barrel; Liquid packaging: 5kg/pot, 20 kg/box, 25kg/new hard plastic barrel.
