Liquid UV-LED Photoinitiators For Faster Curing And Accuracy

Meeting safety and industry standards

UNICURE series

The UNICURE series comprises advanced liquid photoinitiators engineered to deliver efficient and reliable curing performance in modern UV-LED systems. These materials generate free radicals upon exposure to UV or LED light, initiating rapid polymerization in UV-curable formulations. Compared to conventional solid photoinitiators, liquid photoinitiators offer superior handling, improved miscibility, and greater formulation flexibility.

UNICURE photoinitiators are specifically designed for use with narrow-band UV-LED light sources, enabling fast and uniform curing even under lower energy conditions. Their liquid nature ensures homogeneous distribution throughout the formulation, resulting in consistent surface cure, reduced defect formation, and enhanced overall film quality.

Optimized for compatibility with a wide range of acrylate monomers and oligomers, UNICURE products support high-performance formulations across inks, coatings, adhesives, and functional resins. They provide reliable radical generation, improved curing efficiency, and stable processing behavior across diverse application environments.

FAQs

Can these specialty chemicals be used in pigmented coatings?

Yes, they are fully compatible with both clear and pigmented systems. Also, they maintain consistent cure performance and formulation stability.

How do they improve formulation homogeneity?

The best part of the liquid form of the synergists is the uniform distribution within the formulation, such as coatings, inks and adhesives. Thus, it provides better overall homogeneity.

Will they affect colour or clarity in clear coatings?

No, these Liquid UV-LED Photoinitiators maintain optical clarity in clear systems. Also, they provide a reliable surface cure and a better finish.

Are they easy to handle during formulation?

Yes, the liquid form simplifies handling, processing and integration into formulations. Thus, this series can be easily used for industrial applications.

Are they optimised for different UV-LED curing wavelengths?

Yes, our liquid UV-LED photoinitiators are optimised for UV-LED curing wavelengths and are compatible with LED-UV and Mercury UV systems.
