It contains a damping agent – either water or alcohol – in a quantity of not less than 25 per cent by weight, as required by law, or a gelatinizing plasticizer in a quantity of not less than 18 per cent by weight. Ranges and typical application areas are as follows: Nitrogen Grade: Nitrogen Range: Typical Application: Low Nitrogen Grade (L) 10.7% - 11.2%: Printing Inks: Medium Nitrogen Grade (M) 11.2% - 11.7%: Printing Inks, Film … These are starting point formulations, some adjustment will be required in order to optimize these formulations for a specific application. If you have any questions or need support, please contact our experts. Elvacite® 4086A – Hard, medium viscosity grade for plastic coatings providing improved resistance to alcohol based cleaners. Principal polymers In water based inks, two types of acrylic polymers are used: • Polymers in emulsion or dispersion, which improve the drying, gloss, adhesion and water resistance of inks. Coating formulations based on physically drying binders such as nitrocellulose, require external plasticizers for optimal film formation. To avoid the formation of air bubbles, the printing materials were loaded using a spatula into a 3 mL syringe having attached a cylindrical nozzle … The properties of flexographic inks obtained by the partial replacement of nitrocellulose (NC) resin with different amounts of polyurethane (PU) resins were evaluated for the statistical planning of mixtures to develop an optimum ink formulation. I need formulation guide for my 100 % toluene based ink. Ethyl acetate . The inks were extruded using the PH2 print-head (pneumatic driven print-head, DD135 N). IMS 99%. Here we demonstrate the promise of nitrocellulose as a synergistic polymer stabilizer for graphene inks … Nitrocellulose with alcohol appears as a white solid mixed with ethanol or another solvent to form a slurry.
