Extension of knowledge points:

Ultraviolet curing ink, namely uv ink, refers to the use of ultraviolet light of different wavelengths and energy to polymerize the monomers in the ink binder into a polymer under ultraviolet irradiation, so that the ink can be filmed and dried.

UV curable inks have brilliant colors (except in special cases), good printability, and suitable curing and drying rates. At the same time, it has good adhesion, and has the characteristics of wear resistance, corrosion resistance and weather resistance.

UV curing ink generally includes the following basic components.

Color: Make the ink color reach the appropriate density and intensity.

Oligomer: First of all, we must ensure the wetting of the pigment, and make the pigment have good transferability, printability, and film-forming properties.

Thinner: Adjust the viscosity and viscosity of the ink to maintain the curing rate.

Photoinitiator: Choose the combination of photoinitiator to make it have sufficient curing speed under the conditions of use.

Additives: A variety of different additives are used in the UV ink formulation to control the performance of the product, such as ink flying, thixotropy, wettability and anti-foaming.
