Improved Descaling Efficiency
Counteracts the effects of dissolved calcium coming from the hard water and prevents scale from reacting with the ingredients of inks or fountain solutions. Can easily replace EDTA in formulation.
Improved Bleed Control
Glycolic Acid reduces bleed and enhances wetting, flow, and the gloss of the ink. It also helps absorb titanium dioxide and enables better suspension and fixation of inks onto the substrate. Acts as a penetrant by penetrating the substrate vertically and decreases the lateral spreading of the ink. Glycolic Acid allows for uniform area fills and improved color quality while maximizing light-fastness without sacrificing printing reliability using any conventional technique.
Glycolic Acid does not boil at high temperatures like other organic acids. It is an effective organic acid in ink jet inks, especially when formulated with pH sensitive colorants to inhibit color migration. Glycolic acid can be used as a primary or secondary acid in the fountain solution which also acts as the buffering agent to maintain constant pH throughout the formulation.
Provides pH Staibility
Glycolic acid can be used as a primary or secondary acid in the fountain solution which also acts as the buffering agent to maintain constant pH throughout the formulation.
