PureTech Scientific Glycolic Acid Benefits For Inks

Improved Descaling Efficiency

Glycolic acid is highly efficient in counteracting the effects of dissolved calcium from hard water, consequently preventing scale from reacting with the ingredients of inks or fountain solutions. This property makes glycolic acid a viable alternative to EDTA in formulations, offering an eco-friendly and effective descaling solution. 

Quality Coloring and Appearance

Glycolic acid enhances the color quality and appearance of inks by reducing bleed and improving wetting, flow, and gloss. Its ability to absorb titanium dioxide facilitates better suspension and fixation of inks onto various substrates, resulting in more vivid and durable prints. 

Improved Bleed Control

In terms of functionality, glycolic acid penetrates the substrate vertically, which significantly decreases the lateral spreading of the ink and allows for uniform area fills. Consequently, it improves color quality while maximizing light-fastness without sacrificing print reliability, even with conventional printing techniques. 

Enhanced Efficacy

Glycolic acid does not boil at high temperatures like other organic acids. It is an effective organic acid in inkjet inks, especially when formulated with pH-sensitive colorants to inhibit color migration.

Buffering and pH Stability

Glycolic acid serves as an excellent primary or secondary acid in fountain solutions, ensuring a constant pH throughout the ink formulation process.
