Durability in the Good Excellent 3X5 Flags Wholesale
Water-based ink composition by the following components: resin (water-soluble resin, colloidal dispersion, emulsion polymers), the water solvent (ammonia, chamber class), pigments (organic pigments, inorganic pigments), cosolvent (alcohol, B glycol ether), additives (refer to solvent-based ink) and water.

Resin. The classification of water-soluble and water reducible resin, as shown in Table 3-10, the nature of these resins, such as shown in Table 3-11.
a) water-soluble resin. 3X5 Flags Wholesale Water-soluble resin is not the main raw material, its purpose is: to adjust the ink viscosity and mobility; stable dispersion; given pigment dispersion; give the film shape of the ink ink and pigment fixation of the performance.
b) the colloidal dispersion. The colloidal dispersion is an intermediate state between the water-soluble and emulsified. Polar molecule colloidal dispersion by adjusting the pH and the addition of cosolvent, Custom Flags And Poles enable solubility and viscosity changes. Its alkali soluble, acid soluble, and three non-ionic resin. Less soluble best for the manufacture of water-based ink. Alkali-soluble acrylic resin for its diversity and good physical and chemical properties, 3X5 Flags Wholesale the most value in use as a water-based ink links.
c) emulsion polymers. Rich emulsion polymers can ink film strength, the opposite in the ink, stability, flow, gloss, etc. on the version and speaking in front of the water-soluble resin and colloidal dispersion compared to worse, so it is necessary with other resin and to compensate for these shortcomings.
Pigments. Pigment is basically the same as used with solvent-based inks, Custom Flags For Boats but the alkaline water-based ink, so to use alkali-resistant pigments.
Water solvent. The role of water solvent is dissolved alkali soluble resin, and the general use of ammonia and amines.
Cosolvent, and other. Cosolvent of water-based inks are generally alcohol, ethylene glycol esters. Its functions are: to reduce the surface tension of water-based ink, 3X5 Flags Wholesale to improve the degree of wetting of the substrate; improve the solubility of the resin, to maintain a proper viscosity; and adjust the drying speed.
In addition, water-based ink used raw materials, defoamers, preservatives, anti-rust agents, abrasion agents, plasticizers, and dispersants.
(b) the nature, use and dry.
a) General nature. Diluted with water to the of water-based ink, the ink film after drying water-resistant; low odor, non-combustible, pollution-free; image reproduction is good, graphic distinctive; 3X5 Flags Wholesale suitable than solvent-based ink, no network trace, blistering, pinholes, spots; adhesion material widely applicable. flag makers
b) use the method. Ink water or designated diluent . Water resistance and solvent resistance, strong plates should be used.
