Introduction
2-Phenoxy ethyl acrylate (PHEA) is a versatile monomer widely used in UV-curable coatings, inks, adhesives, and other specialty chemical formulations. With the global UV coatings market projected to reach USD 7.47 billion by 2035 (CAGR 5.2%) , demand for high-performance additives like PHEA is surging. This article explores the chemical properties, industrial applications, and market significance of PHEA, with a focus on Shenzhen U-Sunny's AM-311, a leading product in this sector.
Chemical Properties of 2-Phenoxy Ethyl Acrylate
PHEA (CAS 48145-04-6) is an acrylate ester with a molecular formula of C11H12O3 and a molecular weight of 192.21 g/mol. Key characteristics include:
Low viscosity (5–15 cps at 25°C), ideal for diluting oligomers and adjusting formulation viscosity .
High refractive index (1.516), enhancing optical clarity in coatings and adhesives .
Low acid value (≤0.5 mg KOH/g) and excellent hydrophobicity, improving water resistance and shelf stability .
Fast curing speed and low shrinkage, critical for precision applications like electronics encapsulation .
These properties make PHEA a cornerstone in UV formulations, balancing performance, cost-effectiveness, and environmental compliance.
Applications in UV Coatings, Inks, and Adhesives
