The printing industry is constantly seeking faster, more efficient, and environmentally friendly solutions. Ultraviolet (UV) curable inks have revolutionized printing processes by offering rapid drying, excellent adhesion, and vibrant finishes. Central to the performance of these inks is the photoinitiator, a compound that absorbs UV light and triggers the polymerization process. Among the most effective and widely used is 1-Hydroxycyclohexyl phenyl ketone.

As a premier chemical supplier based in China, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality 1-Hydroxycyclohexyl phenyl ketone, a key component for optimizing UV ink formulations. This article highlights its importance and the benefits it brings to the printing sector.

What are UV Curable Inks?

UV curable inks are liquid formulations containing monomers, oligomers, pigments, and photoinitiators. When exposed to UV light of specific wavelengths, the photoinitiator absorbs this energy and generates reactive species (free radicals or cations) that initiate a rapid polymerization reaction. This process crosslinks the ink components, instantly solidifying the ink layer on the substrate. This contrasts sharply with solvent-based inks, which rely on evaporation, a slower and less energy-efficient process.

1-Hydroxycyclohexyl Phenyl Ketone: Enhancing Ink Performance

1-Hydroxycyclohexyl phenyl ketone, often known as Photoinitiator 184, is a type I photoinitiator that plays a crucial role in the effectiveness of UV inks. Its key attributes include:

  • High Reactivity and Efficiency: It effectively initiates the polymerization of acrylate-based inks, allowing for faster printing speeds and improved through-cure, even in pigmented formulations. This is vital for maintaining high-volume production.
  • Non-Yellowing Properties: Crucial for applications requiring color fidelity, such as printing on light-colored or clear materials, or for inks where maintaining a clean white or pastel shade is essential. This photoinitiator ensures that the printed colors remain true over time.
  • Good Solubility: It readily dissolves in common ink vehicles, ensuring homogeneous mixtures and preventing issues like pigment aggregation or uneven curing.
  • Low Odor and Migration: For inks used in packaging or food-related applications, low odor and low migration characteristics are important considerations, and Photoinitiator 184 generally performs well in these aspects when properly formulated.

When printers seek to buy 1-Hydroxycyclohexyl phenyl ketone, they are looking for a reliable ingredient that ensures their UV inks perform consistently, offering sharp prints, vibrant colors, and excellent durability.
