81UV B50 Blue is used for direct printing on to various hollow articles made of polyethylene (PE) and polypropylene (PP) such as cartridges, bottles, cans, tubes etc. Pre-treatment for PE and PP is essential. These inks show good adhesion and high chemical resistance. 81UN is especially suitable for printing on to plastic sports bottles, these inks are not effected by condensation which is a known issue with most inks. This very highly reactive UV ink is primarily processed as a 1 component ink on quick running, multi-colour presses for container printing. The high gloss finish inks come in a ready-to-print formulation or alternatively can be processed with UV-H hardener for applications requiring outstanding resistances. 81UV is classified as low migration inks according to EUPIA Directive (exception N50). For details please refer to the technical Data Sheet. 81UV is a higher viscosity ink suitable for slower running machines but if lower viscosity is required (eg. faster running machines) 80UV is recommended.
