Lexajet
DESCRIPTION
Lexa JET UV inkjet inks is for use in piezoelectric, DOD print heads. These inks provide high flexibility and elongation as well as excellent adhesion with good chemical resistance to recommended substrate.
Primary uses of Lexa JET UV inkjet inks is natural Leather , PU , TPU and industrial substrate where flexibility and elongation is of importance
Main advantage of LexaJET
UV inkjet inks are as follows
- UV curable printing inks without solvent.
- Formulated for use flexibility and elongation.
- Formulated high performance pigments for highest chroma
- Excellent light fastness(pigments are all 7-8 on Blue Wool scale)

* Accelerated weathering test by Xenon Arc Weather meter
* Can be 24 month exposure in outdoor
- Fast curing speed.
- Abrasion resistance.

Curing Parameters
LexaJET UV inkjet inks are formulated to cure when exposed to a focused , medium pressure mercury vapor lamp providing 225 – 300 mJ/cm² and 600W/cm². The actual level of cure will depend on ink thickness , substrate , and UV curing lamps being used. Superior through cure may be obtained by reducing the print speed to increase the overall UV dose. The inks will undergo dark cure at room temperature or an optional thermal post -cure at 200°C for 5 minutes or less may be required. Further recommendation on obtaining best cure could be provided depending on the end user application.
