Advantages of water-based ink leveling agents
The advantages of water-based ink leveling agents are mainly reflected in improving the quality of printed products, optimizing ink performance, enhancing construction convenience and meeting environmental protection requirements. The following is a specific analysis:
1. Improve the quality of printed products
Eliminate surface defects
By reducing the surface tension of the ink, the leveling agent can make the ink spread evenly on the printed substrate, eliminate defects such as brush marks, orange peel, pinholes, and make the surface of the printed product smoother and flatter. For example, in plastic film or paper printing, the leveling agent can significantly reduce ink accumulation and stains, and improve the clarity and color vividness of the pattern.
Enhance adhesion and durability
The leveling agent can enhance the wetting ability of the ink on the printed substrate, help the ink to better adhere to the substrate, reduce ink shedding, and improve the durability of the printed product. This advantage is particularly important in printed products such as food packaging and labels that need to be stored or used for a long time.
2. Optimize ink performance
Improve leveling and wettability
The leveling agent reduces the surface tension of the ink, making it easier to spread the ink during the printing process, achieving a better leveling effect. At the same time, it can also enhance the ink's wetting ability on the printed substrate, which helps the ink to better penetrate and adhere to the substrate.
Improve the dispersibility and stability of the ink
Some leveling agents (such as fluorocarbons) have extremely low surface energy, which can significantly reduce the surface tension of the ink, improve the dispersibility of the pigment, and control the overflow and floating of the pigment, thereby stabilizing the ink system and extending the storage period and service life of the ink.
3. Enhance construction convenience
Improve printing efficiency
Leveling agents can improve the fluidity and wettability of the ink, make the printing process smoother, reduce problems such as clogging and oblique spraying, and improve printing speed and efficiency. This advantage is particularly obvious in high-speed printing or continuous production.
Extend the service life of equipment
By reducing the residue and accumulation of ink on the printing equipment, the leveling agent can reduce the cleaning frequency and maintenance cost of the equipment and extend the service life of the equipment. For example, in roller printing, the leveling agent can keep the roller clean and reduce the adhesion and wear of the ink.
4. Comply with environmental protection requirements
Reduce VOCs emissions
As a water-based system additive, water-based ink leveling agent can significantly reduce the emission of volatile organic compounds (VOCs) compared to solvent-based leveling agents, reduce harm to the environment and human body, and meet the requirements of modern green chemistry and environmental protection regulations.
Safe and pollution-free
Some leveling agents are made of environmentally friendly materials such as polyether modified silicone, which are pollution-free to the environment and have no irritating odor during use, which is conducive to improving the working environment and protecting the health of workers.
