UViprim FL

UViprim FL, ink with UV drying dedicated to printings on rigid or semi-rigid bottles of flamed polyethylene or polypropylene.Ink with UV drying dedicated to printings on rigid or semi-rigid bottles of flamed polyethylene or polypropylene.Excellent stability of the ink in the screen with a high reactivity during the curing process.NVP FREE.


Substrate treatment

UViprim FL is formulated to print on PE and PP used in the bottle industry. The surface tension is very low, it is necesarry to flame the substrate before printing (minimum 42mN/m). The surface to be printed needs to be clean without grease particles.



UViprim FL is a highly-reactive single-component ink. Under a lamp of 160 – 200 W/cm, the ink cures at a rate of between 2500 and 4000 units per hour.
The tape resistance test should only be performed after the complet cooling of the bottle at ambient temperature.
The overlaying of colours must be done in line on multi-colour printing machine.
Adding 5% of hardener (representing 5% of the ink weigh) improves water resistance and solvents resistance, as well as encouraging a better adherence to difficult substrates. The effectiveness of the hardener can be observed 24 hours after printing.
The combination of the ink and the hardener mixture stable for 8 hours.
The speed of curing depends on numbers of parameters, including the thickness deposited and the opacity, colour and nature of the substrate.
Due to the various printing configurations, testing is essential before each new printing run.
The mesh required will be from 140 to 180 threads/cm.
UViprim FL inks are ready to use. If the viscosity nevertheless needs to be reduced.
