Low viscosity wet good soft ink resin LuCure7598.

Product Description
UV ink refers to the UV ink in ultraviolet light, absorb different wavelengths of energy curing drying film of an environmentally friendly ink, it is almost all printing methods have a wide range of applications, such as: UV offset ink, UV offset ink, UV screen ink, UV inkjet ink, UV gravas ink and UV printing ink and so on.
present, Runo Chemical has successfully developed a three-function modified polyester acrylic LuCure7598, mainly used in soft and gravate inks, but also for offset printing and other inks. The resin has the characteristics of clear rutting, low viscosity, low odor, and does not contain any organic volatiles

. Runo Chemical Technology Center has done a series of tests on the resin. The relevant data are summarized below for informational purposes only.
Test Method
Transparent varnish system, a single resin with a small amount of acrylic monosome, moderate amount of light trigger, test performance differences,
color ink system, the use of a single resin with the appropriate amount of thinner and light trigger combination, and add a four-color pigment powder, grinding into the corresponding ink system, to investigate the resin curing speed, adhesion, fluidity, pigment wetting and other properties.
experiments show that LuCure7598 has the following characteristics:
curing speed
LuCure7598 resin in the light curing power of 500-1000mJ/cm2 conditions, whether it is varnish colorless transparent system, or add colored ink system, have a good drying speed.
resilience and impact resistance are
. LuCure7598 is coated with 15 microns of plastic film and, after drying, repeatedly cracks without exploding ink. As a three-function polyester resin, curing contraction is small, the fat family structure of the middle chain segment strongly ensures that the whole has good toughness and impact resistance, can be applied to the field of bending testing with very high requirements.
moisture and fluidity of pigments
by adding 10-30% organic pigments to the resin system, grinding and polishing. It is confirmed that LuCure7598 has good wetting dispersion to the four-color pigments, especially for the grinding of organic blue pigments, and that the resin has good fluidity both in the transparent varnish system and in the colored ink system.
adhesion
adhesion properties are one of the most important features of a UV resin, and we took this into account when synthesizeing the LuCure7598 design. We have all kinds of PP-PVC-ABS-PC and other plastic materials, as well as some commonly used in the market on the gold and silver paper, and the market conventional UV resin have carried out parallel comparison testing, confirmed that LuCure7598 pairs of hard-to-attach substrate has a good adhesion.
