摘要

Coating composition, process for preparing a gas barrier of lamella; gas barrier of lamella lamella lamella;; multilayer; container formed of a packaging material for food and gender; pharmaceutical product packaged or any other material sensitive to SFX Sfera composition coating comprising a polyvinyl alcohol sililatado and colloidal silica in a veu00edcuThis aqueous, where the solid content of the composition is not more than 7.5% WLW, the content of polyvinyl alcohol sililatado silila monomer is not more than 3.0% (based on the monomers forming the polyvinyl alcohol sililatado), polyvinyl alcohol sililatado comprising at least 50% w / W of the solid content of the composition, and the average size of the particles of the colloidal silica is from 5 to 80nm, and may be coated on a substrate with a layer of a The inorganic compound to form a gas barrier laminate.
