Application of oil-repellent agent in printing ink

Application of oil-repellent agent in printing ink

The application of oil-repellent agent in printing ink is mainly reflected in the following aspects:

1. Improve ink performance

Enhance oil resistance:

The main function of oil-repellent agent is to enhance the oil resistance of ink and prevent the ink from being contaminated by grease during the printing process, thereby ensuring the quality of printed products.

Prevent shrinkage and fish eyes:

Contaminants in the ink may cause defects such as shrinkage or fish eyes on the surface of the printed product. Oil-repellent agent can prevent the occurrence of these defects and make the surface of the printed product smoother and more beautiful.

Improve leveling:

Oil-repellent agent can reduce the surface tension of ink and improve the leveling of ink, so that the ink can be better spread on the surface of the substrate during the printing process.

2. Broaden the scope of application of ink

Applicable to a variety of substrates:

Since oil-repellent agent can enhance the oil resistance and leveling of ink, the ink can be applied to more types of substrates, such as metal, plastic, glass, etc.

Applicable to different printing methods:

The addition of oil-repellent agent enables the ink to adapt to different printing methods, such as offset printing, gravure printing, flexographic printing, etc., to meet different printing

needs.

3. Improve printing efficiency and quality

Reduce printing failures:

The addition of oil-repellent can reduce failures caused by ink problems during printing, such as poor ink drying and adhesion, thereby improving printing efficiency.

Improve the quality of printed products:

By preventing defects such as shrinkage cavities and fish eyes, and improving the leveling of inks, oil-repellent can significantly improve the quality of printed products.

4. Specific use methods and precautions

Use methods:

Oil-repellent can usually be added at any stage of the ink production process, but it needs to be stirred evenly to ensure its effect. The amount added should be adjusted according to the ink system and specific needs.

Precautions:

When using oil-repellent, pay attention to its compatibility with the ink system. Some oil-repellents may have limited compatibility in some ink systems, so tests should be conducted before use to determine the appropriate amount of addition.

In addition, during the storage and transportation of oil-repellents, attention should also be paid to moisture-proof, acid-base and other impurities to prevent mixing, so as not to affect its performance.

In summary

The application of oil-repellent in printing inks can significantly improve ink performance, broaden the application range of inks, and improve printing efficiency and quality. When using it, attention should be paid to its compatibility with the ink system as well as measures to prevent moisture, acid and alkali during storage and transportation.
