How does uv ink remove the irritating smell?

   The irritating smell of UV ink first comes from the slow release of r

aw materials under specific conditions. After UV ink is cured, formaldehyde

and sulfur irritating gases will be generated during the decomposition of

raw materials such as initiator and resin. At this stage, most of the irritating

smell of UV ink printing is mainly the volatiles released before and after

the UV ink itself is solidified.

react completely, there will be no reactive "acrylic acid" component, forming

a pungent acidic odor. In addition, if the monomer is low molecular weight,

low boiling point, etc., it can emit odor at room temperature, especially most

monofunctional monomers, such as acrylic acid diester. However, the solid

components used by UV ink are basically odorless, such as pigments, fillers,

waxes, etc., so it is unnecessary to consider. If the monomers and resins used

in UV ink are of good quality, there will be no problem with the smell. In general,

UV initiators are the main source of the irritating smell of UV inks, because UV

inks often need to add a variety of initiators to completely dry and cure.

   How do UV ink manufacturers remove the irritating smell contained in UV ink?

At present, there are hundreds of kinds of initiators used by UV ink manufacturers

in the market, but the efficiency, price, color shadow and scope of use vary greatly.

In order to reduce the odor of the initiator, it is enough not to use such initiator.
