1 FEATURES Cont…..

For applications requiring a wax / silicone free ink please order DR-0 series inks.

For compliance with Nestle Guidance Note on Packing Inks please order DR-2 Series.

(Curing conditions, ink applications and substrate do have an impact on final printing results, we therefore recommend to conduct a trial run and get the food packing tested and certified by a third-party audit).

2 CURING:

DR-1 inks are highly reactive yet press-stable, delivering predictable curing and adhesion results when exposed at a running speed of e.g. 600 units per minute to UV lamps of 160 Watts per cm.

3 SUBSTRATES

We recommend to achieve optimum printing results by using a pre-treatment by either CORONA or Flame.
PE, PS, PVC & ABS > 38 dynes per cm PET > 42 dynes per cm.
PP & PPCP > 44 dynes per cm.

4 AUXILLIARIES

Our ready to use inks can be mixed with:

Tack Reducer	Recommended 1-3%	Reduces tack
PI Additive	Recommended 1-3%	Increases cure speed
Slip Additive	Recommended 1-2%	Improves scratch resistance
Scuff Additive	Recommended 1-2%	Improves scuff

5 PACKING

DR-0/1/2 inks are packed in 1 KG (NET) black plastic cans with 12 x 1 KG per box.

6 STORAGE & SHELF-LIFE

DR-0/1/2 inks should be stored in a cool, dry, well ventilated covered area.
Ambient temperature should be between 20-25 degrees Celsius.
Avoid direct sunlight.
Under these conditions and in its original container, the shelf-life of DR-0/1/2 inks is 12 months from the date of production indicated on the label.
Excess ink from the press should be stored separately and its stability monitored.
Several factors during printing will reduce the shelf-life.
Check thoroughly if reusing.
Desatec does not guarantee the shelf-life of excess ink, ink that has not been stored in the specified conditions or ink that has been modified in any way.
