Acrylic emulsion is widely used in printing inks. Here are its main functions and advantages: Enhance adhesion Acrylic emulsion can form a strong bond with various substrates (such as PET, BOPP, PE plastic films and paper), ensuring that the ink does not come off easily after printing. It is particularly suitable for packaging printing. Enhance glossiness and color spreadability It can make the surface of the printed product present a high gloss, while improving color saturation and clarity, enhancing the visual effect. It is often used in high-end packaging, labels and other products with high requirements for glossiness. Improve printing adaptability It has good leveling property and drying speed, can reduce ink flying, bubbles and other problems during the printing process, improve production efficiency and printing quality, and is especially suitable for high-speed printing equipment. Superior environmental performance As a water-based emulsion, acrylic emulsion has a low VOC (volatile organic compound) content, complies with environmental protection regulations, and reduces harm to the environment and human health. Chemical resistance and wear resistance The formed ink film has good water resistance, oil resistance and friction resistance, prolonging the service life of the printed product, and is suitable for outdoor or frequently exposed packaging materials. Application examples: Water-based plastic ink: used for plastic film printing, such as food packaging, daily use labels, etc. Water-based paper intaglio ink: suitable for paper printing, providing good color performance and adhesion. Aluminum coating water-based clear varnish: protects the aluminum substrate, enhances gloss and corrosion resistance. Notes: The performance of different types of acrylic emulsions varies. It is necessary to select the appropriate product based on specific printing requirements (such as substrate type, glossiness requirements, environmental protection standards, etc.), and optimize the formula through experiments Sinograce Chemical has been established for over 15 years and is dedicated to the research and development, production, sales and application promotion of high-tech functional materials.

Macromolecular colorants are a new type of colored macromolecular polymers formed by introducing coloring groups into the main chain or side chain of macromolecules through certain chemical reactions. They have many advantages such as high safety and non-absorbability by the human body, and are a kind of environmentally friendly products that can save energy, reduce emissions and lower consumption. Since its synthesis,polymer dyehave always been regarded as a type of functional colored macromolecular compound. They not only possess the light absorption properties of small molecule colorants, but also exhibit the stability of polymers. This combination endows the macromolecular colorants with dual functions: namely, the large molecular size, high strength, easy film-forming property, solvent resistance, migration resistance, heat resistance, processability, as well as the strong absorption of light and the color diversity of the organic colorants. In recent years, the research on macromolecular colorants has made rapid progress and has now become a new field in functional polymers andcolor chemistry. Macromolecular colorants not only possess the general functions of small molecule colorants, but also have many special advantages. For example, when the polymer framework is combined with traditional food pigments, and the molecular weight reaches above 3000, it will not be absorbed by the human digestive system. It will be excreted through the intestines and will not cause harm to the human body, making it safer. The coloring agent raw material is a functional raw material and has the following advantages: Good resistance to migration. The large molecule colorants do not undergo molecular migration in the dyed substances, thus avoiding color mixing contamination. Excellent heat resistance. The non-volatile and high melting point nature of the large molecule, combined with its low solubility at high temperatures, makes it have better heat resistance. High safety. The large molecular chain size makes it unable to penetrate the skin and will not be absorbed by the human body, achieving the safety level for oral use. Strong resistance to solvents. The large molecule colorants do not dissolve in most common solvents or have very low solubility, making them less prone to fading. Good compatibility. The molecular framework used is the same as that of the dyed high molecular materials, significantly improving compatibility. Green and environmentally friendly. The water-based high molecular materials are prepared based on water-based high molecular synthesis technology, truly achieving green and environmentally friendly properties. Anhui SinograceChemical's large molecule colorants are safe and environmentally friendly, dedicated to being a color chemical manufacturer.
