For procurement managers and R&D scientists in the chemical and manufacturing sectors, identifying and sourcing high-quality raw materials is a critical task. Photoinitiator ITX, identified by CAS number 5495-84-1, is a prime example of such a chemical. This powerful compound plays an indispensable role in UV curing applications, driving efficiency and enabling advanced material properties. Understanding how to procure it effectively is crucial for ensuring supply chain stability and product quality.

Photoinitiator ITX, chemically known as 2-Isopropylthioxanthone, is a Type II photoinitiator valued for its ability to initiate rapid polymerization when exposed to UV light, especially when paired with amine synergists. Its effectiveness spans across a wide array of industries, making it a sought-after commodity. For procurement professionals, key considerations when sourcing ITX typically revolve around purity, consistency, reliable supply, and competitive price points.

Key Specifications to Consider:

  • Purity: High purity levels, often specified as ≥99.0%, are essential to guarantee consistent performance and avoid unwanted side reactions in sensitive formulations. Manufacturers should provide detailed Certificates of Analysis (COA).
  • Appearance: Typically a pale yellow to light yellow powder, its visual consistency is an important initial quality indicator.
  • Melting Point: A defined melting point range (e.g., 56 – 72°C) is indicative of product integrity and can be a crucial parameter for formulators.
  • Solubility: Its good solubility in common organic solvents and UV curable monomers is a significant advantage for ease of integration into various formulations.

Applications Driving Demand:

The demand for Photoinitiator ITX is robust due to its widespread application:

  • UV-Curable Coatings: From wood finishes to industrial protective layers, ITX ensures rapid and durable film formation.
  • Printing Inks: Essential for high-speed printing, ITX enhances adhesion, scratch resistance, and gloss in flexographic, screen, and offset inks.
  • Adhesives & Sealants: Facilitates quick bonding in UV-curable formulations used in electronics, automotive, and construction.
  • 3D Printing: A key component in photopolymer resins for additive manufacturing, enabling precise object creation.

Finding a Reliable Supplier:

When looking to purchase Photoinitiator ITX, especially in bulk quantities, identifying a trustworthy manufacturer or distributor is paramount. Key factors include:

  • Manufacturer Reputation: Look for suppliers with a proven track record and established presence in the chemical industry.
  • Supply Chain Reliability: Ensure the supplier can meet your required volumes consistently and deliver within stipulated timelines. This is particularly important for continuous production runs.
  • Pricing and Quotation: Obtain detailed quotes that reflect market prices and discuss potential volume discounts. A transparent pricing structure is a good indicator of a reliable partner.
  • Technical Support: Access to technical data sheets (TDS) and responsive customer service can be invaluable for R&D teams and troubleshooting.

For businesses in need of this critical UV curing additive, partnering with experienced chemical suppliers who understand the nuances of international trade, quality control, and logistics is essential. By focusing on these procurement criteria, you can secure a consistent supply of high-quality Photoinitiator ITX (CAS 5495-84-1) to meet your manufacturing needs.
