Improve Your Uv Curables With Cellulose Esters

Aside from aiding in flow out and wetting, Eastman cellulose esters (CEs) provide additional UV stability and enhance gloss in UV curing systems. CEs are compatible in a wide range of solvents and many common acrylate monomers, including UV-reactive monomers, to resist shrinkage.

BENEFITS OF CELLULOSE ESTERS

UV curable inks are experiencing rapid growth and adoption due to the many advantages they offer. Higher productivity due to fast dry times makes the UV printing process more economical. However, the trade-off can be poor flow out or wetting, which can lead to adhesion issues. Cellulose esters from Eastman can help overcome these adverse effects.

Cellulose esters (CE’s) are versatile formulating tools that work in various printing platforms including offset, rotogravure, flexographic and inkjet. Compatible in a wide range of solvents, CE’s increase adhesion, modify rheology, and improve leveling and flow of inks. Eastman’s cGMP compliance allow ink and coating formulations for direct and indirect food contact.
