Evatane®4260
EVA4260 is a high VA ethylene-vinyl acetate (EVA) resin from ARKEMA, France.
1-Transparency
EVA 4260 is a brand developed specifically for transparency suitable for varnishes.
2. Self-adhesive
The 4260 low self-adhesion of EVA ensures the prevention of resin blocking and the stability of the ink.
3. Solubility
-Easily dissolved in aromatic compounds, such as toluene, benzene,-xylene, solubility of up to 45% at room temperature, and maintain
Low viscosity of the solution.
-Partially soluble in ketones, up to 15% at room temperature.
-Insoluble in alcohol.
4. Stability
Easy to store, no precipitation.
The higher polarity of EVA resin (VA content 42%) can improve the adhesion of the ink to the BOPP film after surface corona treatment.
The EVA resin contributes to improving the adhesion to the primer.
EVA resin can also provide a part of the mechanical strength of the film, flexibility.
