First, the application
1, suitable for printing ink industry:
1) solvent-based inks used in Metal complexing dye;
2) Metal complexing dye inks used for aluminum foil;
3) printing inks used in other paper or metal surface with Metal complexing dye (such as screen printing);
2, for the coatings industry:
1) Metal complexing dye coatings used;
2) aluminum foil coloring of Metal complexing dye (such as gold foil material);
3) Metal complexing dye transparent colored metal used (such as indoor decorations baking finishes);
4) The special coating with Metal complexing dye;
3, applies to other industries:
1) Metal complexing dye pen and ink used in all kinds of stationery;
2) Plastic products surface staining with Metal complexing dye (such as vacuum plating, etc.);
3) Metal complexing dye natural and synthetic leather surface coloring purposes;
4) Metal complexing dye stained with shoe polish;

Second, the performance
1, the series has a variety of powder and liquid form, the liquid color fine concentration of about 30%.
2, the product features:
1) excellent solubility, a wide range of solvent selection;
2) with a variety of resins have good compatibility;
3) colorful;
4) has excellent acid, alkali and heat resistance;
5) Superior complex dyes, no free heavy metal;
6) Liquid dyes (color fine) easy to use, no dust pollution.

Third, pay attention
1, the series dye solubility in different solvents of different performance by the temperature, the resin, the purity of solvents and other effects when dissolved. According to the respective process requirements, to conduct experiments before use to understand their solubility in this solvent.
2, after the dye is dissolved, there will be long-term placement of trace substances in precipitation, so the application about 300-400 mesh filter to prevent the precipitation of substances into the next process when access.
3, the time of dissolution, the solvent is metered into the dissolving vessel, preferably the solvent is suitably heated to 40-50 ℃, and then the dye is added in batches, stirring constantly a few minutes after the addition was completed, waiting for 1-2 hours, then stir , static precipitation. If undissolved make dye, can then add an appropriate amount of solvent extract usable dye drained the remaining unwanted impurities.
4, when used, should pay attention to choose the best solvent and dissolution method, or cause can precipitate more color precision, low dye content, dyed shades and other adverse consequences. This series of dyes should be selectively used to high-grade metal paint.

Fourth, packaging and transportation
1, Packaging: 1) 25KG / barrel or 5KG / box (powder), carton or drum packaging
2) 25KG / drum or 20KG / barrel (liquid), a new thick-walled hard plastic pail.
2, Transportation: agency, or home delivery.
