For professionals in the chemical industry, particularly those involved in material science and formulation, understanding the specific properties and applications of key chemical compounds is essential. Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-2,4,6-tris(1-phenylethyl)phenoxy-, ammonium salt, identified by its CAS Registry Number 119432-41-6, is one such compound that plays a significant role in modern industrial processes, most notably in UV curing technologies.

Chemical Profile and Functionality

This complex chemical structure, often referred to by trade names such as Sorpol T 10SPG or Soprophor 4D384, belongs to the class of ethoxylated polyarylether sulfates. Its molecular design, featuring a hydrophilic sulfonate head and a hydrophobic tristyrylphenyl tail linked by a polyethylene glycol chain, grants it excellent surfactant properties. In UV curing applications, these properties are leveraged to enhance the performance of formulations used in inks, coatings, and adhesives. Its primary functions often include:

  • Emulsification and Dispersion: It effectively emulsifies and disperses hydrophobic components, such as photoinitiators and pigments, within aqueous or solvent-based UV-curable systems. This ensures a homogeneous mixture, critical for consistent curing.
  • Wetting and Leveling: As a wetting agent, it improves the surface contact between the formulation and the substrate, leading to better adhesion and smoother finishes.
  • Stability Enhancement: It contributes to the overall stability of the formulation, preventing phase separation during storage and application.

Applications in UV Curing

The versatility of CAS 119432-41-6 makes it a valuable additive in a wide array of UV-curable products. Procurement managers and R&D scientists often seek this compound for:

  • UV Inks: Improving pigment dispersion and flow properties for high-quality printing on various substrates.
  • UV Coatings: Enhancing scratch resistance, gloss, and adhesion in industrial, automotive, and decorative coatings.
  • UV Adhesives: Providing stable, high-performance bonding solutions for electronics and other demanding applications.
