UViprim Eco Plus

UViprim Eco Plus ink with UV drying dedicated for printing on papers, cardboards, PVC for PLV. NVP FREE.

UViprim ECO Plus ink has been formulated in order to print on the following sustrates:

• Vinyl adhesive
• Paper, cardboard
• Supple and stiff PVC

The new UViprim Eco Plus ink allows multi layer printings without weakening the substrate.
Main characteristics are:

• Ready to use inks
• Highly glossy
• High reactivity
• Large suppleness allowing the cutting in the ink film
• Good resistance from outside

Polymerisation

The opaque white must be used alone whereas, diluting white can be used with other colourings with a 10 to 20% rate in order to get a correct opaqueness. The UViprim Eco Plus ink is used at delivery viscosity or slightly diluted, with 150-34 fabrics. The line colours polymerise between 20 and 40 m/min on PVC, in 150-34 under an 80 W/cm lamp.
On paper, under the same conditions, the passage speeds are halved.
As the chemical reaction continues, it is better not exceed 24 hours between each layer.
Moreover, adherence between the different colours,sometimes, must be check.
The polymerization speeds depends on the thickness deposited, the colour and the type of substrate, the type and number of UV lamps.
Due to the various printing configurations, it will better to perform some tests.
