China Manufacturer Pentaerythritol Triacrylate / Peta CAS 3524-68-3 with Stock

UV Monomer PETA (Chemical name: Pentaerythritol Triacrylate, CAS: 3524-68-3) is a high-functionality trifunctional acrylate monomer.
As a highly reactive multifunctional monomer, PETA is primarily used as a crosslinking agent and reactive diluent. Its molecular structure contains three polymerizable acrylate double bonds, enabling the formation of a highly crosslinked polymer network during radiation curing. This characteristic significantly enhances the hardness, abrasion resistance, chemical resistance, and heat resistance of the cured material, while also imparting good adhesion and gloss to the coating. Its core application areas include UV-curable coatings (such as those for wood, PVC, and metal), high-performance inks, adhesives, electronic encapsulation materials, and the rapidly developing field of 3D printing photosensitive resins.
