In the realm of UV-curable coatings and inks, the selection of the right photoinitiator is paramount for achieving optimal performance. Photoinitiator 1173, chemically known as 2-hydroxy-2-methylpropiophenone (CAS 7473-98-5), stands out as a highly effective and widely utilized Type I free radical photoinitiator. Its unique properties make it an indispensable component in formulations across various industries, from printing to protective coatings.

Photoinitiator 1173 is celebrated for its excellent efficiency in initiating the polymerization process when exposed to UV light. This rapid initiation translates into faster curing times, a critical factor for manufacturers looking to boost production throughput and reduce energy consumption. The chemical structure of 2-hydroxy-2-methylpropiophenone allows it to readily absorb UV radiation and generate free radicals, which then propagate the crosslinking reaction within the monomer and oligomer matrix of the formulation.

One of the significant advantages of Photoinitiator 1173 is its low yellowing characteristics. This attribute is particularly valuable in applications where color stability and aesthetic appeal are crucial, such as clear coatings for wood furniture, automotive finishes, and high-gloss inks. Unlike some other photoinitiators, it minimizes post-cure yellowing, ensuring that the final product maintains its intended color and clarity over time, even when exposed to sunlight or elevated temperatures.

The versatility of 2-hydroxy-2-methylpropiophenone extends to its excellent compatibility with a wide range of acrylate-based monomers and oligomers. This broad compatibility allows formulators to easily blend it with other photoinitiators and additives to fine-tune curing speeds, surface properties, and overall performance. As a liquid photoinitiator, it also simplifies handling and incorporation into liquid formulations, reducing processing complexities for manufacturers.

For businesses seeking to purchase Photoinitiator 1173, partnering with a reliable manufacturer and supplier in China can offer significant advantages in terms of both quality and cost-effectiveness. Sourcing from a reputable supplier ensures access to high-purity material (typically ≥99.0% assay), which is crucial for consistent performance. Prospective buyers are encouraged to inquire about pricing and availability to secure their supply chain for this essential chemical.

In summary, Photoinitiator 1173 is a cornerstone chemical for UV curing technologies. Its efficiency, low yellowing properties, and broad compatibility make it a preferred choice for UV paints, inks, and coatings. For companies looking to optimize their UV curing processes, understanding the benefits of this powerful photoinitiator and securing it from a trusted China manufacturer is a strategic move.
