UViprim GL

The mono-component UViprim GL range is based on a DUAL CURE system (UV light + oven drying). It is dedicated to a high speed screen printing on glass, with or without coating, for interior use. The dual cure system makes these inks insensitive with the extra thickness obtained on objects having a broad dimensional tolerance. Most of all, Uviprim GL inks are glossy, highly reactive and chemically resistant.The mono-component UViprim GL range is based on a DUAL CURE system (UV light + oven drying).

Supports and pretreatments

The quality of glass and its chemical structure are related to its manufacturing method. Its surface quality will have to be perfect i.e. free from release agent or any other residue (finger marks, dust, grease, silicone etc).
Untreated glass:
A flame treatment (surface tension > 44 mN/m) according to the UVitro® process (trade mark of ISIMAT GmbH) is necessary to obtain maximum performances.
Coated glass:
Many glass containers are covered with a water or solvent-based coating to modify the surface aspect (colour, opalescent, scratch resistance…): a flame treatment, right before printing, is then essential to obtain a sufficient surface tension and thus a good adherence.

Curing conditions

Being based on a DUAL CURE system, this ink dries in two steps: under UV  light, to obtain a dry ink surface and to authorize the immediate overprinting of it, and with hot air to obtain optimal chemical and physical resistances.

  • UV drying: at a printing speed of 3600 prints/h, use a lamp of 180-200W/cm minimum.
    Oven drying: only one 20 min at 165°C passage for the whole of the decoration.

The performances of the system are function of the material and the products used. Its industrial validation is imperative before final production run.
