Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
The vibrant world of colored coatings and inks is often achieved using pigments, which are essential for achieving desired aesthetics and opacity. However, for industries utilizing ultraviolet (UV) curing technology, pigments can present a significant hurdle. They can absorb and scatter UV light, impeding the polymerization process and leading to incomplete curing. This is where the selection of the correct photoinitiator becomes paramount. For manufacturers looking to buy the best solutions, understanding the role of Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (CAS 162881-26-7) is key.
The Pigment Problem in UV Curing
Pigments, by their very nature, are designed to interact with light. In UV curing, this interaction can be detrimental. Common pigments like titanium dioxide (TiO2), used extensively for its whitening and opacifying properties, are particularly problematic as they absorb and scatter UV light very effectively. This scattering reduces the amount of UV energy that reaches the photoinitiator molecules distributed within the resin. Consequently, the initiation of the polymerization process is inefficient, leading to surface tackiness, poor hardness, and incomplete cure throughout the film.
Phenylbis(2,4,6-trimethylbenzoyl)phosphine Oxide: The Pigment-Ready Photoinitiator
This is where Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide shines. As a highly efficient photoinitiator, it possesses a broad absorption spectrum that extends into the longer UV and visible light regions (up to 405 nm). This spectral characteristic allows it to absorb UV radiation that would otherwise be blocked or scattered by pigments. By absorbing light that passes through the pigment particles, it efficiently generates the free radicals necessary to initiate polymerization, even in heavily pigmented systems. As a leading manufacturer and supplier in China, we offer this vital ingredient to help your formulations succeed.
