Description

Pentaerythritol Tetraacrylate (PETA) is a high-functionality, tetra-acrylate ester monomer that serves as a critical building block for creating highly cross-linked polymer networks. Its four reactive acrylate groups enable rapid curing and the formation of dense, durable materials with excellent chemical and thermal resistance. This multifunctional acrylate is essential for formulators in the coatings, inks, adhesives, and photopolymer resin industries seeking to enhance hardness, scratch resistance, and cure speed in their final products.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent in formulations for wood, plastic, and metal coatings, as well as graphic arts and printing inks, providing fast cure and superior surface hardness.
• Photopolymer Resins: Used in stereolithography (SLA) and digital light processing (DLP) 3D printing resins to create rigid, high-resolution models and functional prototypes.
• Adhesives & Sealants: Imparts strong adhesion and cross-link density in anaerobic, cyanoacrylate, and radiation-curable adhesive systems.
• Fiber Optic Coatings: Employed in the primary and secondary coatings of optical fibers to provide a protective, durable layer.
• Dental Composites: Acts as a cross-linking monomer in light-curable dental restorative materials, contributing to strength and wear resistance.
• Electronics: Used in solder masks, conformal coatings, and dielectric materials for printed circuit boards (PCBs).
• Overprint Varnishes: Enhances gloss, abrasion resistance, and chemical durability in protective coatings for packaging.

Quality Control

Our Pentaerythritol Tetraacrylate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and assay, gas chromatography (GC) for residual monomer and solvent content, and colorimetry (APHA). We provide comprehensive Certificates of Analysis (COA) with each shipment to ensure traceability and compliance with your specifications and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. For long-term storage, consider under an inert atmosphere (e.g., nitrogen) to minimize polymerization risk and maintain product integrity.
