The Use of Anthracene Derivatives in UV-LED Curing

Thanks to its lower operating costs, UV-LED has become a popular choice for end users looking to cure coatings, inks and adhesives. But commonly used UV-LED lamps aren't compatible with most photoinitiators, making it difficult for formulators to provide the right resin composition. So, what's the answer?

One potential solution is the use of anthracene derivatives. Download our RadTech presentation to learn how these photoinitiators that can increase cure speeds and decrease initiator usage in free radical-based systems.

Basics of UV Cationic Curing

From productivity to sustainability, light and low-energy electrons offer several advantages for curing coatings. But while the industry has focused on free radicals, cationic curing has been largely overlooked, despite key benefits like low shrinkage and improved adhesion.

Is cationic curing right for your applications? Find out by downloading a brief introduction, including basic chemistry, key materials, formulating strategies and hybrid systems.

Kawasaki Kasei ANTHRACURE
This "Japanese-quality" premium line of photosensitizers enhances absorption at longer wavelengths for radical-UV, cationic-UV, and hybrid-UV formulations—helping to cure thicker coatings or inks, which are often used in high-margin, premium applications.

Denacol® EX-52
For cationic-UV and hybrid radical-/cationic-UV formulations where strength and toughness are desired, Denacol® EX-252 is a critical component. Pairing with oxetane monomers (which enable fast reactivity) provides a powerful combination of properties in a formulation that also exhibits good weatherability.

Clyclomer M100
This hybrid methacrylate/cycloaliphatic epoxy monomer is a unique reactive diluent that offers superior physical properties compared to similar hybrid-functionality diluents such as Gycidyl MethAcrylate (GMA). With a viscosity of only 9cP at 25°C, Cyclomer M100 imparts excellent diluency properties combined with a strong cycloaliphatic backbone and does not contain any chlorine, so it is well suited for electronics applications. Cyclomer M100 may also be considered as a raw material for synthesizing oligomers that contain cycloaliphatic epoxy functionality, by radically polymerizing the methacrylate groups.

Light Acrylate POB-A
This acrylate monomer demonstrates a High Refractive Index (RI) of 1.566 while imparting flexibility and very low irritation. Its low viscosity (18cP at 25°) enables wide formulation capabilities along with ease of handling. POB-A is an excellent reactive diluent for optical coatings and adhesives as well as other applications such as inks and adhesives where RI is not critical but flexibility, low irritation and low viscosity are desired.

VEEA
A hybrid vinyl ether/acrylate monomer with an exceptionally low viscosity (3.65cP), VEEA is a reactive diluent perfect for UV-InkJet applications. Along with low irritation, the presence of both acrylate and vinyl ether functionalities enables both radical- and cationic-UV curing as well as good adhesion properties for a range of UV-curable applications.
