JONCRYL LMV 7014
An acrylic colloidal emulsion that provides excellent resolubility
and good ink transfer for cost-effective corrugated ink formulations. It can be used as a sole vehicle for carbon black ink or as a letdown vehicle for organic pigment color dispersions.

JONCRYL® LMV low-maintenance, acrylic water-based polymer emulsions
JONCRYL LMV low-maintenance, water-based acrylic polymers for printing inks reduce print waste by providing clean printing and excellent pH stability without sacrificing resistance properties.
Industry studies show that total press downtime in a flexible packaging operation can be as high as 50%. Of that downtime, 20% is “ink related.” JONCRYL LMV resin solutions and emulsions allow ink makers to offer printers and converters an alternative to current water-based technology and reduce waste and downtime due to anilox plugging and ink build-up on plates. JONCRYL LMV pH-stable polymers, when used to make low VOC inks for paper, film, and foil inks, provide a balance of clean printing, resolubility, and excellent pH stability without sacrificing resistance properties.
Resolubility
Inks based on Joncryl LMV 7000 series polymers have excellent resolubility on press. This benefit has a direct correlation to the amount of waste that a press generates when the ink dries in the cylinder after a process upset or other shutdown.
Figure 1 shows that inks based on Joncryl LMV 7031 recoveredtheir original print density in less than four minutes, whileconventional water-based polymers took considerably longerto recover. In this test, the print cylinder was allowed to dry for10 minutes. The press was restarted and the time to developthe original print density was recorded.
Stability
Joncryl LMV 7000 series polymers maintain pH over long press runs —even on light coverage print jobs.
Figure 2 illustrates the excellent pH stability of inks based on Joncryl LMV 7040 emulsion. Inks were formulated with Joncryl LMV 7000 series polymers and compared with standard water-based polymers. The pH of the Joncryl LMV-based inks remained stable over the entire run.
