Blue Pigment: PB15:3/PCN

Ciba Corporation

Irgastab UV 10: A new type of ink additive that ensures the long-term stability of inks and varnish, as well as the ink stability from production to printing, coating and curing over the entire cycle. As a stabilizing agent, it can effectively control the gelation problem of the UV-curable components with little adverse effect on the curing speed.
Irgacure 379: Can meet the fast curing requirements of multiple inks based on photolithographic tolerance formulations.
Irgacure 2100 is a multi-functional, liquid composite photoinitiator that is primarily suitable for UV pigmented inks. It ensures that UV inks or varnish will only produce a slight yellowing and a small residual odor after curing.
Irgacure 2022: Based on Irgacure 819

A new multi-functional liquid complex photoinitiator synthesized by Irgacure 819 (diacylphosphine oxide) can be applied to UV pigment inks in most spectral ranges.
Irgacure 250: A liquid cationic photoinitiator compound for UV-curable pigment inks and varnish, including white base oils and adhesives, such as white base oils and adhesives for labels, flexible packaging, and posters. .
Darocur ITX, EDB and EHA: The addition of Darocur ITX, EDB and EHA further expands Ciba's development and application of pigments and energy curing.

General Press Colors

New UV-backing pigment series: General Press Colors developed 12 types of primers in 2003. In 2004, the company also improved it to develop more color-based primers. This series of products can meet the requirements of fast and stable curing, and at the same time improve the friction resistance, gloss, and extend the shelf life. In the fast printing, it also reduces the occurrence of ink flying phenomenon. These primers use common pigment fillers and are more versatile and more standardized.

Kustom Corporation

Lithomaster offset energy curing adhesive: This material has excellent rheological properties and greatly improves the UV and EB printing effects of webs. The binder has great advantages for controlling the ink-water balance.

KS-284: A pigment dispersion binder for offset printing and flexographic printing inks. This product effectively reduces the thixotropy of the ink during pigment dispersion and is suitable for those sensitive to odors.

Sartomer

Novel Monomers and Oligomers: In May 2004, Sartomer introduced 5 new raw materials that can be used in UV inks, including a variety of monomers and oligomers. Many tests have shown that it has a viscosity. Low, good pigment wetting properties, small odor, good stability and heat resistance, high Tg value and little skin irritation.

Sun Chemical Company

Spectracure F Dispersant: This product plays a role of pigment dispersion in UV flexo printing inks, also suitable for primary colors and PMS printing (Panton matching system, by combining with standard SWOP inks, created more than 3,000 kinds Color number identification system). The most outstanding performance of this product is reflected in the low viscosity maintained during the high-performance pigment-fill mixing process, helping ink manufacturers to produce more high-performance (ink thick and low viscosity) inks.

UCB Corporation

UCB has introduced a number of raw materials for energy-curable inks, including ViaFlex 110, ViaFlex 111, ViaFlex 406, ViaSet 210, ViaScreen 520, ViaScreen 521, and Ebecryl 446. In addition, a number of new photoinitiators have been introduced, such as Additol BP, Additol BDK, Additol HDMAP, Additol CPK, Additol TPO, Additol ITX, Additol DMMTA, Additol EHA and Additol EPD.

ViaFlex 110: A link material designed to solve some of the special problems faced by ruby-color flexo printing inks. This product helps increase color density and reduce ink stickiness.

ViaFlex 111: A link material designed to solve some of the special problems faced by yellow series flexographic printing inks. The product has better dispersion performance and reduces ink stickiness.

ViaFlex 406: is also a special link material for flexographic printing inks, which reduces the ink viscosity while increasing the color strength. At the same time, there are some other properties that have been improved, such as the ink transfer effect when the number of anilox roller lines is high, and the adhesion properties to various synthetic substrates.

ViaSet 210: Universal offset color ink binder. The finished product ink produced by the use of it has the characteristics of good ink viscosity, less ink flying phenomenon and good rheological property while ensuring good pigment wetting performance.

ViaScreen 520/ViaScreen 521: Binder for thermoforming screen printing inks.
