Photoinitiator 184: A Versatile Solution for Photo-polymerization Processes

In the world of photo-polymerization, photoinitiators play a crucial role in initiating and accelerating the cross-linking process of polymers. Photoinitiator 184 (PI-184) is one of the most widely used photoinitiators due to its versatility and efficiency. In this article, we will explore the properties, applications, and benefits of PI-184, a product manufactured and supplied by INNO Specialty Chemicals from China.

Introduction to PI-184

Photoinitiator 184, also known as 1-Hydroxycyclohexyl phenyl ketone, 1-Benzoylcyclohexanol, or 1-Hydroxycyclohexylphenone, is a colorless to pale yellow crystalline solid that is soluble in most organic solvents. It has a molecular weight of 254.31 g/mol and a melting point of 47-50 °C. PI-184 is a Type I photoinitiator, which means it absorbs light at a wavelength of 365 nm and generates free radicals to initiate the polymerization process.

Properties of PI-184

PI-184 has several properties that make it a popular choice for various photo-polymerization processes. Firstly, it has a high reactivity and efficiency, which means it can initiate the polymerization process at low concentrations (0.5-2.0 wt%). Secondly, it has a broad absorption spectrum, which makes it suitable for curing processes that use different light sources, such as UV, LED, and visible light. Thirdly, it has low volatility and odor, which makes it easy to handle and suitable for applications that require low migration and low odor.

Applications of PI-184

PI-184 has a wide range of applications in various industries, including coatings, inks, adhesives, and dental materials. In the coatings industry, PI-184 is used to cure UV-curable coatings for wood, plastics, and metal substrates. It is also used in the automotive industry to cure clear coats and base coats. In the ink industry, PI-184 is used to cure UV-curable inks for digital printing and screen printing. It is also used in the flexographic printing industry to cure water-based and solvent-based inks. In the adhesive industry, PI-184 is used to cure UV-curable adhesives for bonding plastics, glass, and metals. In the dental industry, PI-184 is used to cure dental resins for restorative and prosthetic applications.

Benefits of PI-184

The use of PI-184 in photo-polymerization processes offers several benefits for manufacturers and end-users. Firstly, it enables fast curing and high productivity, which means manufacturers can produce more products in less time. Secondly, it offers excellent adhesion and durability, which means end-users can enjoy long-lasting and high-performance products. Thirdly, it offers low VOC emissions and low odor, which means manufacturers can comply with environmental regulations and end-users can enjoy a healthier indoor environment.

Conclusion

Photoinitiator 184 (PI-184) is a versatile and efficient photoinitiator that is widely used in various photo-polymerization processes. It has several properties that make it suitable for different applications and industries, including high reactivity, broad absorption spectrum, low volatility, and low odor. Its use offers several benefits for manufacturers and end-users, including fast curing, high productivity, excellent adhesion, and low VOC emissions.
