Photoinitiator 379

Product Overview

Photoinitiator 379 represents a advanced class of alpha-aminoketone compounds specifically engineered for high-performance ultraviolet curing applications. As a Norrish type I photoinitiator, it exhibits exceptional cleavage efficiency upon exposure to UV radiation, generating free radicals that initiate polymerization rapidly. This chemical is widely recognized in the industry under alternative names such as Irgacure 379 and is valued for its ability to deliver deep cure profiles even in pigmented systems. Our manufacturing process ensures consistent molecular integrity, making it a reliable choice for formulators demanding precision and repeatability in their production lines.

Key Performance Features

The selection of an appropriate photoinitiator is critical for achieving optimal coating properties. Photoinitiator 379 offers a distinct advantage over traditional benzophenone-based systems due to its reduced odor profile and minimal yellowing characteristics after curing. Key technical benefits include:

• High reactivity across a broad spectrum of UV wavelengths.
• Excellent solubility in various acrylate monomers and oligomers.
• Low volatility ensures minimal weight loss during the curing process.
• Superior through-cure capabilities for thick film applications.
• Enhanced stability during storage under recommended conditions.

Technical Specifications

Quality control is paramount in the production of fine chemical additives. Each batch of Photoinitiator 379 undergoes rigorous analytical testing to verify compliance with international standards. The following table outlines the typical physical and chemical properties expected from our premium grade material. Customers can request a Certificate of Analysis (COA) for specific lot verification upon purchase.

Industrial Applications

This photoinitiator is primarily utilized in the formulation of UV-curable inks and coatings where speed and quality are essential. It is particularly effective in offset printing, letterpress, flexographic, and screen printing inks based on multifunctional acrylates. Beyond printing, it serves as a vital component in wood coatings, plastic coatings, and paper varnishes. The compound enables manufacturers to achieve high line speeds without compromising on the hardness or adhesion of the final cured film. Its compatibility with various resin systems makes it a versatile drop-in replacement for older generation initiators.

Storage and Handling

To maintain optimal performance, Photoinitiator 379 should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Containers must remain tightly closed when not in use to prevent moisture absorption or contamination. Standard industrial safety precautions apply during handling, including the use of appropriate personal protective equipment.
