Product Overview
Photoinitiator 184, chemically known as 1-Hydroxycyclohexyl Phenyl Ketone, stands as a premier Type I radical photoinitiator utilized extensively across the industrial coating and printing sectors. As a high-efficiency alpha-hydroxy ketone derivative, this compound facilitates rapid polymerization under ultraviolet radiation, making it indispensable for modern UV-curable systems. Our manufacturing process ensures exceptional purity levels, minimizing residual impurities that could affect the final product performance or aesthetic quality.
Designed for versatility, Photoinitiator 184 offers a balanced profile of reactivity and stability. It is particularly valued in formulations where color stability is critical, as it exhibits minimal yellowing even after prolonged exposure to sunlight or aging. This characteristic makes it a preferred choice for clear coats, white pigmented systems, and applications requiring long-term durability.

Industrial Applications
The primary utility of Photoinitiator 184 lies in its ability to initiate free radical polymerization in acrylate-based systems. It is extensively employed in the production of UV-curable varnishes for paper, metal, and plastic substrates. In the printing industry, it serves as a key component in lithographic inks, screen printing inks, and flexographic inks, ensuring fast drying times and high gloss finishes.
Furthermore, this photoinitiator is highly recommended for wood coatings and plastic coatings where aesthetic clarity is paramount. It is also compatible with adhesive formulations and electronic product coatings. For optimal performance, it is often used in conjunction with other photoinitiators or UV absorbers, depending on the specific thickness and opacity requirements of the coating layer. The typical recommended dosage ranges from 2% to 5% by weight relative to the total formulation.
Key Performance Advantages
- Superior color stability with negligible yellowing over time.
- High photoreactivity ensures rapid curing speeds on production lines.
