Does water-based ink contain acetone
Date: Aug 28 2023 From: Star Color
Water-based inks are acetone-free, and acetone is generally used as a solvent in oil-based inks.
Water-based ink is an ink that uses water as a solvent, which is more environmentally friendly than traditional solvent-based inks.Compared with traditional solvent-based inks, water-based inks have higher advantages in environmental protection, safety, health and other aspects, so they are widely used in the printing industry.
Flexographic water-based ink is a widely used water-based ink in flexible printing, which has good printing performance and high reducibility of color , and is therefore widely used in fields such as food packaging, beverage packaging, cosmetics packaging, etc.Compared to traditional solvent based inks, flexographic water-based inks have better environmental friendliness and printing quality, making them increasingly popular in the printing industry.
What is acetone?
Acetone is an organic compound with the formula C3H6O.It is a colorless, transparent liquid with a pungent odor.Acetone has good solubility and can dissolve a variety of organic substances, so it is widely used in industrial production and chemical experiment.
Acetone is often used in oil-based inks, acetone is usually used as a solvent, mainly has the following two roles:
Dissolve the color paste composition: the pigment, resin and other components of the ink are usually solid or semi-solid, and it is necessary to dissolve it into a flowing state by adding a solvent in order to be evenly coated on the printing material during the printing process.Acetone is a good solvent that can dissolve many ink components, resulting in better ink fluidity and lower viscosity, making it more suitable for coating during the printing process.
Adjusting ink properties: Acetone can also adjust ink properties, such as adjusting the drying speed and surface tension of the ink.In some cases, adding the right amount of acetone can speed up the drying speed of the ink and improve the printing efficiency.In other cases, adding the right amount of acetone can reduce the surface tension of the ink, making it easier for the ink to be coated on the printed material.
Whether the water-based ink contains acetone
In general, water-based inks do not contain acetone.Because water-based inks use water as a solvent, while acetone is an organic solvent and cannot be used in water-based inks.Compared to traditional solvent-based inks, water-based inks do not contain harmful organic solvents, so they are more environmentally friendly and safe.
However, in some cases, water-based inks may contain small amounts of acetone.For example, in the production of water-based ink, some acetone compounds may be used as catalysts or additives to promote the drying and curing of the ink.However, these acetone compounds are only used as auxiliary materials, the amount of use is very small, and generally will not have a significant impact on the environmental protection and safety of water-based ink.
In summary, water-based ink is a kind of ink that uses water as a solvent, does not contain harmful organic solvents, and has better environmental protection and safety.Flexographic water-based ink is a widely used water-based ink in the fields of food packaging, beverage packaging, cosmetics packaging, etc.Although in general, water-based inks do not contain acetone, in some cases, water-based inks may contain small amounts of acetone.Therefore, when using water-based inks, it is necessary to pay attention to selecting products that meet environmental standards and follow safe usage regulations to ensure the safety and environmental friendliness of the printing process.
Additionally, it should be noted that when using water-based inks, it is necessary to ensure that their quality meets printing requirements.The quality of water-based ink directly affects the printing quality. If the ink quality is not good, it may lead to poor printing effect and affect product quality.Therefore, when choosing water-based inks, it is necessary to choose brands with reliable quality and mature production processes, and follow relevant printing processes and operating standards to ensure printing quality and safety.
