Description

Polyester Acrylate/Methacrylate, Peam-541 is a specialized oligomer designed for high-performance radiation-curable formulations. This compound is valued for its ability to impart excellent adhesion, flexibility, and chemical resistance to cured films and coatings. It is a critical raw material for formulators and manufacturers in the UV/EB-curable coatings, inks, and adhesives industries seeking to enhance product durability and processing speed.

Application

• UV-Curable Industrial Coatings: Used as a key oligomer in wood, plastic, and metal coatings for furniture, automotive parts, and consumer electronics.
• Flexographic and Screen Printing Inks: Provides excellent pigment wetting and film flexibility for high-speed printing applications.
• Overprint Varnishes (OPV): Enhances gloss, scratch resistance, and chemical durability on packaging materials.
• Adhesives and Sealants: Serves as a reactive diluent and backbone resin in instant-cure adhesive systems.
• 3D Printing Resins: A component in formulations for stereolithography (SLA) and digital light processing (DLP) to achieve precise, tough parts.
• Optical Fiber Coatings: Contributes to the protective secondary coating layer due to its balanced mechanical properties.

Quality Control

Our Polyester Acrylate/Methacrylate, Peam-541 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance in radiation-cure applications, including viscosity, acid value, color, and functional group analysis. A Certificate of Analysis (COA) documenting these parameters is provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat sources and incompatible materials. For long-term storage, a nitrogen blanket is recommended to maintain optimal quality.
