For professionals in the coatings industry, selecting the correct photoinitiator is paramount to achieving desired curing speeds, film properties, and overall product performance, especially when dealing with pigmented formulations. Pigments, by their nature, can absorb or scatter UV light, posing a significant challenge to efficient curing. This is where advanced photoinitiators like Difunctional Alpha Hydroxy Ketone (CAS 71868-15-0) come into play. As a leading manufacturer and supplier based in China, we understand the critical role this product plays in modern UV curing technology.

Difunctional Alpha Hydroxy Ketone, often referred to as Photoinitiator 160, is a Type I free-radical photoinitiator. Its chemical structure is engineered to offer superior reactivity compared to conventional alpha-hydroxy ketones. One of its most significant advantages is its ability to shift its absorption spectrum to longer wavelengths. This characteristic is vital for pigmented systems because many common pigments absorb strongly in the shorter UV wavelengths typically used. By absorbing effectively at longer wavelengths, Difunctional Alpha Hydroxy Ketone can penetrate deeper into the coating film, ensuring thorough curing even when high pigment loads are present.

The benefits of using this photoinitiator extend beyond its spectral properties. It also offers excellent coating properties, contributing to smooth, uniform finishes. Furthermore, it is highly valued for applications where low Volatile Organic Compounds (VOCs) and low migration are critical requirements. This makes it an ideal choice for sensitive applications such as food packaging inks and coatings for consumer goods, where safety and regulatory compliance are non-negotiable. If you are looking to buy high-quality Difunctional Alpha Hydroxy Ketone, sourcing from a reliable manufacturer in China like us ensures consistent quality and supply stability.

When considering your next formulation, particularly for challenging pigmented UV coatings, explore the benefits of Difunctional Alpha Hydroxy Ketone. Its capacity to enhance curing efficiency in colored systems makes it a strategic choice. We invite you to request a quote and sample to experience the difference. Partner with a trusted supplier for your critical photoinitiator needs and elevate your product performance.
