In the dynamic world of printing, UV-curable inks offer significant advantages, including rapid drying, enhanced durability, and vibrant finishes. At the heart of this technology is the photoinitiator, and Photoinitiator 1173 (CAS 7473-98-5) is a standout choice for many ink manufacturers. As a leading supplier of specialty chemicals, understanding the precise needs of R&D scientists and procurement managers in the ink industry is our priority.

What Makes Photoinitiator 1173 Ideal for UV Inks?

Photoinitiator 1173, also known by its chemical name 2-hydroxy-2-methylpropiophenone, is a Type I photoinitiator. It excels at initiating free-radical polymerization upon exposure to UV light. For UV inks, this translates to:

  • Fast Curing Speeds: Essential for high-speed printing processes, allowing for immediate handling of printed materials.
  • Excellent Adhesion: Contributes to the ink's ability to bond strongly to various substrates, including plastics, paper, and metals.
  • Minimal Yellowing: Crucial for color fidelity, especially in lighter-colored inks or when printing on transparent materials. This property ensures the integrity of the printed image over time.
  • Good Compatibility: It blends seamlessly with other photoinitiators and monomers, offering formulators flexibility to fine-tune ink properties.

Applications in Printing Technologies

The versatility of Photoinitiator 1173 makes it suitable for a wide range of printing applications:

  • Screen Printing: Ideal for producing durable graphics and functional coatings on various surfaces.
  • Lithographic Printing: Enhances the performance of UV inks used in commercial and packaging printing.
  • Flexographic Printing: Contributes to the rapid curing needed for high-volume label and packaging production.

Sourcing Photoinitiator 1173: Key Considerations for Buyers

When you need to buy Photoinitiator 1173, especially in bulk quantities, partnering with a reliable manufacturer in China is often the most strategic decision. Look for suppliers who can offer:

  • Consistent Quality: Ensure the product meets strict purity standards (e.g., ≥99.0% assay) for predictable results in your ink formulations.
  • Competitive Pricing: Leverage the manufacturing advantages of China to secure cost-effective raw materials.
  • Reliable Supply: A stable supply chain is critical for uninterrupted production.
  • Technical Data: Access to detailed Technical Data Sheets (TDS) and Safety Data Sheets (SDS) is essential for formulators.
