Photoinitiator 784: The Key to Efficient and Reliable Photopolymerization

Photoinitiators are essential components in photopolymerization, a process widely used in the printing, coating, and electronics industries. They generate reactive species upon exposure to light, which trigger the crosslinking or polymerization of monomers or oligomers. Photoinitiator 784, also known as PI-784 or FMT, is a highly efficient and versatile photoinitiator that has gained popularity in recent years. In this article, we will explore the properties, applications, and benefits of PI-784, and why INNO SPECIALTY CHEMICALS is the go-to supplier for this product.

Properties of Photoinitiator 784

PI-784 belongs to the family of alpha-ketosulfones, which are known for their high reactivity and solubility in common solvents. Its chemical structure contains two functional groups: a ketone and a sulfonyl chloride. Upon light irradiation, the ketone group undergoes a Norrish type I reaction, producing a radical cation and a neutral radical. The sulfonyl chloride group acts as an electron acceptor, stabilizing the radical cation and enhancing the efficiency of the initiation process.

PI-784 has a broad absorption spectrum, ranging from 250 to 400 nm, with a maximum at around 365 nm. This makes it compatible with various light sources, such as UV lamps, LED, and laser diodes. Its photobleaching rate is relatively low, meaning that it can sustain multiple exposures without significant loss of activity. PI-784 is soluble in many organic solvents, including acetone, ethyl acetate, methanol, and toluene. Its typical concentration ranges from 0.5 to 5% by weight, depending on the application and the monomer system.

Applications of Photoinitiator 784

PI-784 is a versatile photoinitiator that can be used in various photopolymerization systems. It is particularly suitable for radical polymerization of acrylates, methacrylates, vinyl monomers, and styrenics. It can also initiate cationic polymerization of epoxides and oxetanes, as well as thiol-ene and thiol-yne click reactions. PI-784 is compatible with many additives, such as sensitizers, co-initiators, stabilizers, and chain transfer agents, which can modify its performance and properties.

PI-784 is widely used in the graphic arts industry, for example, in UV-curable inks, coatings, and adhesives. It provides fast curing, high gloss, and excellent adhesion to various substrates, such as paper, plastic, and metal. It can also improve the scratch and abrasion resistance of the cured films. PI-784 is also applied in the electronics industry, for instance, in the fabrication of printed circuit boards, optical fibers, and microfluidic devices. It allows precise patterning, high resolution, and low shrinkage of the polymer structures. PI-784 is also used in the dental and medical fields, where it enables the production of biocompatible and sterilizable materials, such as dental composites, implant coatings, and drug delivery systems.

Benefits of Photoinitiator 784

PI-784 offers several advantages over other photoinitiators, such as benzophenone, thioxanthone, and camphorquinone. Firstly, it has a high initiation efficiency, meaning that it can generate more radicals per photon than other initiators, leading to faster and more complete polymerization. Secondly, it has a low odor and low migration potential, which reduces the risk of contamination and toxicity. Thirdly, it has a high compatibility with different monomers and solvents, which allows for the formulation of custom-made systems with specific properties. Fourthly, it has a low cost and a long shelf-life, which makes it a cost-effective and reliable option for industrial applications.
