SAIB (sucrose acetate isobutyrate) mainly optimizes ink performance and printing quality through its chemical properties in printing, with the following specific functions:

? ? ? ?1.Enhance ink hydrophobicity and image clarity

SAIB can be added as a hydrophobic agent to ink formulations to reduce the diffusion of ink on printing media such as paper, thereby improving the edge clarity and detail expression of printed images. For example, in metal plate printing, its hydrophobic properties can reduce unexpected adhesion between ink and the printing plate, ensuring accurate image transfer.

?

? ? ? ?2.Improve ink smoothness and anti clogging properties

SAIB can adjust the viscosity of ink, reduce the risk of ink clogging on nozzles or printing plates during the printing process, and is particularly suitable for high-precision inkjet printing. Meanwhile, its lubricating effect can reduce the wear of printing equipment and extend its service life.

?

? ? ? 3.Improve the wear resistance and durability of the printing surface

By forming a dense protective layer, SAIB can enhance the scratch and friction resistance of printed materials, making it suitable for printed materials that require long-term storage or frequent contact (such as packaging materials, labels, etc.).

?

? ? ? 4.Optimize ink adhesion and diffusion uniformity

SAIB can adjust the diffusion rate of ink on the surface of paper, promote uniform distribution of ink, reduce color difference and smudging, and improve the consistency and saturation of printed colors. This feature is particularly important in offset printing and gravure printing.

? ? ? 5.Assist in the synergistic effect of other printing aids

In composite formulations, SAIB can work synergistically with resin components such as acrylic resin to enhance the glossiness and adhesion of ink, while improving the weather resistance and chemical corrosion resistance of printed materials
