For professionals in the chemical and materials science sectors, understanding the specific properties and applications of key monomers is essential for successful product development. Pentaerythritol Triacrylate (CAS 3524-68-3) is a notable trifunctional acrylate monomer widely utilized for its ability to create high-performance polymer networks. This article aims to provide procurement managers, R&D scientists, and formulators with a comprehensive overview of its chemical characteristics and industrial significance.

Pentaerythritol Triacrylate is characterized by its three acrylate functional groups attached to a pentaerythritol core. This trifunctionality is the foundation of its performance. When subjected to radical polymerization, typically initiated by UV light or electron beams, it forms highly cross-linked structures. These networks exhibit a desirable balance of mechanical strength, flexibility, and resistance to chemicals and UV degradation. The high cross-link density achieved often results in materials with excellent hardness, scratch resistance, and thermal stability. Procurement specialists will find its consistent quality, often specified at assays of 99.0% or higher, a critical factor for predictable outcomes in their formulations.

The primary applications for Pentaerythritol Triacrylate stem directly from these properties. It is a favored component in UV/EB-curable coatings, where it contributes to rapid curing, high gloss, and enhanced durability, making it ideal for industrial finishes, wood coatings, and protective layers. In the adhesives and inks industry, it improves bond strength, adhesion to challenging substrates, and resistance to solvents and environmental factors. Furthermore, it serves as a key cross-linking agent in the formulation of polymer composites and specialty resins, enabling the creation of advanced materials for electronics, automotive, and aerospace industries.

For businesses looking to buy Pentaerythritol Triacrylate, identifying a reliable supplier is paramount. A China-based manufacturer can offer competitive pricing and a consistent supply of high-purity material. Understanding the technical data sheets and ensuring the monomer meets your specific application requirements, such as viscosity, acid value, and inhibitor concentration, will guide your purchasing decision.
