The water-based ink is mainly used in the printing industry. It is flexible and intaglio. The performance of the paint film in the printing process of the ink determines the quality of the printing products, such as the water resistance, anti backtack, scratch resistance, hand feel, gloss, etc. of the ink film. Therefore, it is necessary to add wax lotion into the water-based ink system to improve the performance of the water-based ink.

During the application of wax lotion in water-based ink system, it reacts with resin lotion, and wax lotion gradually transfers to the surface of the ink film, while forming a stable protective layer, which not only reduces the friction coefficient of the paint film, improves the abrasion resistance of the coating, and has a smooth feel, but also changes the contact angle to modify the direction of force on the coating, and improves the scratch resistance of the coating.

The wax lotion specially used for water-based ink has the following properties:
1. Endow ink and paint film with high resistance to wear and abrasion
2. Improve the surface properties of water-based coatings and inks after film formation
3. Used in coatings to improve the water resistance, heat resistance, anti rebound, scratch resistance, and increase the smoothness of the paint film feel
To sum up, when wax lotion is added to the water-based ink system, it will move to the surface of the ink film and form a dense layer. At the same time, due to the high density of wax particles, it will form an excellent protective layer and improve the performance of water-based ink printing process.
