1-Hydroxycyclohexyl Phenyl Ketone (Photoinitiator 184) for UV Coating CAS 947-19-3

Photoinitiator 184 (CAS No.: 947-19-3) is a highly efficient free radical photoinitiator with the chemical name 1-Hydroxycyclohexyl Phenyl Ketone, molecular formula C₁₃H₁₆O₂, and molecular weight 204.26. Photoinitiator 184 is a white crystalline powder at room temperature, with a melting point of 44–50°C and a density of 1.17 g/cm³. It is insoluble in water, but easily soluble in organic solvents such as acetone, ethanol, and dichloromethane. It has good stability to light and heat.

Properties：

1. Photoinitiator 184 can quickly generate free radicals under the action of ultraviolet light, thus effectively initiating polymerization reactions.
2. It is relatively stable at room temperature and is not easy to decompose, so it has a long storage life.
3. It has a lower odor than some other photoinitiators, making it more advantageous in some applications.

Uses：

Photoinitiator 184 is widely used in ultraviolet (UV) curing systems, especially for the rapid curing of acrylate and methacrylate monomers and oligomers. Specific applications include:
Coatings: varnishes and paints on paper, wood, metal and plastic surfaces to improve coating hardness and weather resistance;
Inks: lithographic, screen and flexographic printing inks to accelerate curing and reduce odor residue;
Adhesives and electronic materials: UV adhesives, photoresists and printing plates to ensure rapid crosslinking and precision molding.

1. 1-Hydroxycyclohexyl Phenyl Ketone has low toxicity, but still needs to be used with caution and avoid direct contact with skin or eyes.
2. When storing or operating, keep away from fire and high temperature environment, keep sealed, and store in a cool and dry place.
3. Before use, read the product's safety technical instructions in detail and use and store according to the corresponding operating instructions.
