1,3-propanediol (1,3-PDO) is colorless, Odorless, transparent and viscous liquid, hygroscopic, miscible with water, alcohol and various organic solvents. It is an important organic chemical raw material, mainly used in inks, coatings, cosmetics, pharmaceuticals, antifreeze and other industries.
The application and role of 1,3 propylene glycol in ink:
Ink is an important material used for printing. It combines patterns and patterns through printing or inkjet printing. The text appears on the substrate. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of binder (resin), pigments, fillers, additives and solvents. The physical and chemical properties of ink mainly refer to its density, fineness, transparency, gloss, light resistance, heat resistance, and acid, alkali, water, and solvent (alcohol) resistance.
1,3 Propylene Glycol is a good solvent for inks, and specific co-solvent mixtures of 1.3 Propylene Glycol and low molecular weight polymeric glycols or related compounds or polyol/alkylene oxide condensates are used to contain insoluble pigment dispersions Liquid aqueous ink combinations provide an excellent blend of optimized properties in terms of stability, optical density, viscosity, printing characteristics and printer maintenance issues.
