Photoinitiator 184: The Cornerstone of High-Performance UV Curing

In the rapidly evolving landscape of UV curing technologies, Photoinitiator 184 stands out as a critical component for achieving superior performance in a wide array of applications. Also known by its chemical name, 1-Hydroxycyclohexyl Phenyl Ketone (HCPK), and identified by CAS No. 947-19-3, this versatile compound is a highly efficient free radical type I photoinitiator designed for the polymerization of chemically unsaturated prepolymers, particularly acrylates, in conjunction with mono- or multifunctional vinyl monomers.

Manufactured as a pure white crystalline powder, Photoinitiator 184 boasts an impressive assay of ≥99% and a molecular weight of 204.26500 with the formula C13H16O2. Its precise physical properties, including a melting point of 46-50°C and a density of 1.17 g/cm³, ensure consistent quality and ease of integration into diverse formulations. Key absorption wavelengths at approximately 244 nm, 280 nm, and 330 nm enable it to efficiently harness UV energy, initiating robust polymerization reactions.

The primary function of a photoinitiator is to convert absorbed UV energy into reactive species that trigger the polymerization process. Photoinitiator 184 excels in this role, producing free radicals with high initiation efficiency. This leads to rapid and thorough curing, which is essential for modern high-speed production lines. Beyond its initiation prowess, a distinguishing feature of Photoinitiator 184 is its excellent thermal stability and exceptional non-yellowing properties. This makes it the preferred choice for clear coatings, overprint varnishes, and other applications where long-term color stability and minimal discoloration after exposure to sunlight are paramount. Its low odor profile further enhances its appeal for various industrial uses.

The applications for Photoinitiator 184 are remarkably diverse, spanning numerous industries and product categories. It is extensively utilized in:

• UV Curable Coatings: This includes varnishes for paper, metal, and plastic surfaces, plastic coatings, and wood coatings. Its ability to maintain clarity and resist yellowing is particularly valued in high-quality finishes.
• Adhesives: Photoinitiator 184 is a staple in UV-curable adhesive formulations, ensuring strong and reliable bonds that cure quickly under UV light.
• Printing Inks: It is widely adopted in lithographic inks, screen printing inks, and flexo inks, contributing to fast curing times and sharp, durable prints. Its performance extends to specialized applications such as printing plates and photo resists.
• Electronic Products: Given the stringent requirements for precision and stability in electronics, Photoinitiator 184 is employed in various electronic applications where UV curing is critical.

For optimal performance, Photoinitiator 184 is typically added to formulations at a recommended concentration of 2-5% w/w. It can be effectively used by itself or, for enhanced through-cure and overall efficiency, in combination with other photoinitiators, particularly in composite systems. When prolonged outdoor exposure or high UV resistance is required, it can also be synergistically combined with UV absorbers. Our commitment as a leading Photoinitiator 184 supplier is to provide a product that meets rigorous quality standards, ensuring reliability for your specific applications.

Proper storage is crucial to maintain the integrity of Photoinitiator 184. It should be kept in a cool, dry, and well-ventilated place, with containers tightly closed to prevent moisture absorption. Protection from direct sunlight and heat is also essential to preserve its efficacy over time.
