ULTRASOLVE INK: Sustainability and high yields in flexographic printing inks for packaging applications The ULTRASOLVE INK is Oxiteno s line of oxygenated solvents for printing inks that offers high performance and sustainability gains. These products reduce evaporation losses while inks are handled during the industrial printing process of plastic films, both in flexographic and rotogravure printers. The ULTRASOLVE INK line also provides the application with high performance, in addition to excellent solubility and stability to the distinctive ink systems, such as NitrocellulosePolyurethane, NitrocellulosePolyamide, NitrocelluloseFumaric, and NitrocelluloseMelamine, among others. Advantages Higher yields thanks to the more balanced evaporation (less need to replace solvents during the handling process) Broader use of renewable sources Reduction of retardant solvents Low solvent retention Suggested Formulations with the ULTRASOLVE INK line PRODUCT Anhydrous Ethanol (can be biobased) ULTRASOLVE INK L 200 Traditional Dilutant (% M/m) 55 Suggested Formulation (1) (% M/m) 58 20 Suggested Formulation (2) (% M/m) 58 20 ULTRASOLVE INK M 60 18 Characteristics Excellent solvency ULTRASOLVE INK M 90 18 Similar drying time and reduced viscosity compared to the solvents available in the market Excellent color and gloss stability Methyl Ether from Monopropylene Glycol (PM) Isopropanol 15 15 4 4 Compatible with photopolymer cliché materials, similar to the solvents available in the market Ethyl Acetate 15 Low toxicity HAP Free* Total 100 100 100 *Hazardous Air Pollutant EPA, section 112

Study on the emission/replacement of diluents in flexographic inks during the handling process in printers During the printing process of plastic films, a great portion of solvents is lost through evaporation while the ink is handled, what leads to an unbalance in the solvent system and the consequent replenishing of diluents to adjust viscosity. Lab and industrial studies have been carried out to check the behavior of solvents during the printing process. The results of these studies were: Less replenishing of diluents Low solvent retention Excellent organoleptic results in the final packaging Conditions of the studies Machine (Fevaflex8) Printing speed: 120m/min Drying among colors: 50oC Final drying: 57oC Inks: N NitrocellulosePolyurethane NitrocellulosePolyamide Colors = 4color and white plated process Initial Dilution Rate = 35% Substrates = PE, PET and BOPP *Fevaflex is a registered mark of Feva Example of solvent losses while the ink is handled in the machine application Differences of Solvent Losses through Evaporation (% m/m) * 25 20 21 Reduction of more than 20% in solvent losses 15 10 16 PARAMETER TRADITIONAL DILUTANT (%m/m) SUGGESTED FORMULATION (1) (%m/m) 5 Pérdidas de Solventes por evaporación durante el manejo, tras 5 h de impresión 21 16 0 * Quantified by the replenishing of diluent for the adjustment of viscosity in NitroPU ink (color printing process) and PE substrate.

Lifecycle Assessment (LCA)* Through the analysis of the impacts established by the Lifecycle Assessment (LCA), it was possible to conclude that the flexographic printing process performed with the ULTRASOLVE INK line has less impact on the environment in global terms, such as, on global warming. 1 RESEARCH 3 FORMULATION OF FLEXOGRAPHIC INKS 6 PRODUCT USE 4 PRINTING PROCESS 2 MANUFACTURING OF SOLVENTS 5 PRODUCT PACKAGING 7 PACKAGING DISPOSAL *Lifecycle Assessment study carried out in partnership with GP2 Prevention Group for the Prevention of Pollution from the Chemical Engineering Department of the Polytechnic School (University of São Paulo)
