Selection of water-based ink additives

Water-based ink additives

In order to improve the performance of water-based inks, it is necessary to add various auxiliaries, and water-based ink auxiliaries are more important than solvent-based inks. Commonly-used water-based ink auxiliaries include the following.

1 Defoamer: used to eliminate the foam in water-based inks, the amount is generally 1% to 2%.

2 Ink stabilizer: It mainly prevents the ink from coalescence and mold during storage and transportation. It can reduce the viscosity of ink and adjust the pH value of ink. Generally, it uses ammonia or ethanolamine.

3 Others include dispersants, preservatives, leveling agents, slip agents, and cross-linking agents. These agents are used scientifically to improve the weakness of aqueous inks, thereby improving the stability of aqueous inks.
