Product Technical Details

Product Overview

Photoinitiator ITX stands as a cornerstone component in modern ultraviolet curing technologies, specifically designed for free radical polymerization processes. As a thioxanthone derivative, this compound functions as a highly efficient Type II photoinitiator. It operates primarily through a hydrogen abstraction mechanism when exposed to UV radiation, generating free radicals that initiate the curing of unsaturated resins. Due to its specific chemical structure, ITX often acts as a sensitizer when utilized alongside anionic photoinitiators, enhancing the overall reactivity and depth of cure in complex formulations.

Our manufacturing process ensures exceptional consistency and purity, making this product a reliable choice for demanding industrial applications. The compound is particularly valued for its ability to perform effectively in transparent or colored systems, where other initiators might struggle with light penetration or compatibility issues. When combined with tertiary amine complexing agents, such as EDB, ITX delivers optimal curing speeds and final material properties.

  • Electronic Products and Photoresists: Used in PCB manufacturing and protective coatings for components.
  • Wood Coatings and Adhesives: Delivers durable finishes and strong bonding capabilities.

Usage Guidelines and Storage

For optimal results, Photoinitiator ITX is generally recommended at a dosage range of 0.2% to 2% by weight, depending on the specific resin system and thickness of the coating. It is most effective when used in conjunction with amine synergists to maximize radical generation. Regarding storage, this product must be kept in a dry and ventilated warehouse environment. Containers should remain sealed to avoid moisture absorption, and the material must be protected from direct sunlight and sources of ignition. Proper handling ensures the longevity and stability of the photoinitiator throughout its shelf life.
