PRIMER VIKTOR 470 is a special barrier lacquer applicable on soft aluminium foils which are used in the packaging industry to pack processed cheese. It is always used along with HS-LACQUER VIKTOR 70 which is applied on the other side of the aluminium foil. It is not sealable with HSL 70. It is a solvent-type, cellulose nitrate-based lacquer with other additives (anti-blockage, in particular) added.
