             Remarks:

              1、Temperature resistance: Euneothol 0.5% dye into alkyd / uric acid coating, spraying on the aluminum sheet, dry, and then bake for 30 minutes, the sample and the other baked samples (120℃/30min) for comparison.

              2、Lightfastness: DIN 54003(Standard blue scale for wool)as control standard,8:optimum, 1:difference.

              3、Solvent: at room temperature, the dye was gradually added to the 1kg solvent, until it was clear to see insoluble dye so far, water is pure water, ethanol concentration was 99.5%, water / ethanol ratio as the quality ratio of 1:1, PM is 99% propylene glycol methyl ether.

            Special note: Lemon yellow 01 in the water to dissolve and dissolve after the preservation of the temperature is better than 10 degrees Celsius, low temperature and easy precipitation.

             

            二、Product Features

                (1)The product is transparent, complete chromatography, coloring power, light resistance, excellent resistance to weathering, and good thermal stability.

                (2)Environmentally friendly products non-toxic, does not contain the 24 kinds of aromatic amines, does not contain the banned products, product does not contain toxic heavy metals, by Intertek third-party testing and certification, in line with the pack of cigarettes, food packaging, such as direct contact with the human body industry requirements.

                (3)Products can be directly dissolved in water, and soluble in alcohols, ethers, ketones, such as organic solvent, products in the water of the resin system in good solubility, in line with the requirements of water system.

            三、Application Area

                (1)Water Hot stamping film, lined paper, the gold card paper, the transfer of gold cardboard, vacuum direct plating paper, vacuum coating
