Photoinitiator 369

Product Overview

Photoinitiator 369 is a premium alpha-amino ketone type photoinitiator designed for high-performance ultraviolet curing applications. Recognized globally for its exceptional reactivity and stability, this compound serves as a critical component in modern UV-curable formulations. Its chemical structure facilitates efficient free radical generation upon exposure to UV light, ensuring rapid polymerization even in challenging environments. Manufacturers across various industries rely on this material for its ability to deliver consistent curing results while maintaining low volatility and minimal odor profiles.

As a specialized additive, Photoinitiator 369 offers superior absorption characteristics in the near-UV region. This makes it particularly valuable for formulations where deep cure or curing through colored layers is required. Unlike traditional initiators, it exhibits reduced yellowing tendencies, preserving the aesthetic quality of the final coated product. Our supply chain ensures high purity levels, meeting stringent international standards for industrial chemical applications.

Key Specifications

Industrial Applications

The versatility of Photoinitiator 369 allows it to be utilized across a broad spectrum of industrial sectors. It is extensively employed in the production of UV-curable inks for paper, metal, and plastic substrates. Its high sensitivity makes it an ideal choice for high-speed printing processes where rapid curing is essential to maintain production throughput. Furthermore, its low mobility ensures that the initiator remains within the cured film, reducing migration issues that could affect food packaging or sensitive electronic components.

In the electronics industry, this photoinitiator is a key ingredient in solder resist inks and photoresists used for printed circuit board manufacturing. It enables precise patterning and robust protection layers. Additionally, it performs exceptionally well in dark or pigmented systems where UV light penetration is limited. When combined with co-initiators such as UV 184 or UV 651, synergistic effects can be achieved to optimize cure speed and surface hardness. It is also compatible with systems containing UV absorbers, maintaining efficacy without compromising stability.

Advantages and Handling

• Excellent UV absorption range suitable for colored and dark systems.
• Low odor and low volatility for safer workplace environments.
• Minimal yellowing ensures high clarity in clear coats.
• High reactivity reduces energy consumption during curing.
• Compatible with a wide range of monomers and oligomers.

Proper storage is essential to maintain the efficacy of Photoinitiator 369. The material should be kept in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Containers must remain tightly closed to prevent moisture absorption and contamination. We offer flexible packaging options, including standard 25kg drums, with custom configurations available upon request to suit specific logistical needs. As a global manufacturer, we provide comprehensive technical support, including Certificates of Analysis (COA) and formulation guidance to ensure optimal integration into your production processes.
