This guide aims to provide comprehensive insights into Photoinitiator 1173, helping you make informed purchasing decisions. We focus on aspects crucial for procurement managers: understanding product specifications, identifying reliable suppliers, and exploring competitive pricing strategies.

What is Photoinitiator 1173?

Photoinitiator 1173, chemically known as 2-Hydroxy-2-methylpropiophenone, is a liquid photoinitiator renowned for its high efficiency, low odor, and excellent non-yellowing properties. As a Type I photoinitiator, it undergoes unimolecular bond cleavage upon UV exposure, directly generating free radicals that initiate the polymerization of acrylate monomers and oligomers. This makes it indispensable in UV-curable systems, including paints, inks, varnishes, and adhesives.

Key Specifications and Performance Attributes

When sourcing Photoinitiator 1173, several specifications are critical for ensuring optimal performance in your formulations:

  • Appearance: Typically a colorless to light yellow liquid, indicating purity.
  • Assay: A high assay (≥99.0%) is crucial for consistent reactivity and performance.
  • UV Absorption: Its absorption spectrum determines its efficiency with specific UV light sources.
  • Low Yellowing: This characteristic is vital for clear coatings and applications where color stability is paramount, especially after prolonged light exposure.
  • Compatibility: Excellent compatibility with other photoinitiators and monomers allows for flexible formulation development.

Many formulators seek to buy Photoinitiator 1173 specifically for its ability to reduce yellowing in cured films, a significant advantage over other initiators. This makes it an excellent choice for wood coatings, clear lacquers, and protective finishes where long-term aesthetic appeal is required.

Procurement Considerations: Supplier and Pricing

For procurement managers, securing a stable supply of high-quality Photoinitiator 1173 at a competitive price is a primary objective. When looking to buy Photoinitiator 1173, consider the following:

  • Manufacturer Reliability: Partnering with a reputable manufacturer in China ensures product consistency, adherence to quality standards (like GMP, SGS), and a reliable supply chain.
  • Wholesale Pricing: For larger volumes, wholesale pricing from a direct manufacturer can significantly impact cost-effectiveness. Engaging in direct inquiries for price quotes is recommended.
  • Technical Support: A good supplier will offer technical support, including SDS/TDS downloads and application guidance, ensuring you can integrate the product seamlessly into your processes.
  • Logistics: Efficient logistics and secure packaging (e.g., 25 kg/drum) are essential for safe and timely delivery.

As a dedicated supplier of Photoinitiator 1173, we are committed to providing not just a product, but a solution. We understand that cost efficiency is key, and our aim is to offer competitive pricing for Photoinitiator 1173 to our global clientele.

Applications and Formulation Tips

Photoinitiator 1173 is widely used in:

  • UV Paints and Coatings: Especially for wood coatings, furniture paints, and clear coats where non-yellowing is important.
  • UV Inks: For printing applications requiring fast curing and excellent print quality.
  • Plastic Coatings: To enhance surface properties and appearance.

While it can be used alone, Photoinitiator 1173 often performs optimally when blended with other photoinitiators or synergists to achieve specific curing profiles. Typical usage levels range from 1-4% w/w, depending on the specific formulation and curing conditions.
