Description

Ethoxylated Bisphenol A Diacrylate is a high-performance difunctional acrylate monomer widely used in radiation-curable formulations. This compound is valued for its ability to impart excellent hardness, chemical resistance, and adhesion properties to cured polymer networks. It is a critical raw material for manufacturers in the coatings, inks, and advanced materials sectors seeking durable and fast-curing products.

Application

• UV/EB Curable Coatings: A key component in formulations for wood, plastic, and metal coatings, providing high crosslink density and surface hardness.
• Graphic Arts & Printing Inks: Used in UV-curable screen, flexographic, and offset inks to achieve rapid curing and superior abrasion resistance.
• Optical Fiber Coatings: Contributes to the primary and secondary coating matrices, offering essential protective and mechanical properties.
• Adhesives & Sealants: Serves as a reactive diluent and crosslinker in anaerobic, cyanoacrylate, and structural acrylic adhesives.
• Electronics Encapsulation: Employed in potting compounds and conformal coatings for printed circuit boards (PCBs) and electronic components.
• 3D Printing Resins: A building block in stereolithography (SLA) and digital light processing (DLP) resins, influencing toughness and resolution.
• Dental Composites: Used in restorative materials and crown & bridge resins for its biocompatibility and polymerization efficiency.

Quality Control

Our Ethoxylated Bisphenol A Diacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, color, viscosity, and acid value are provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is light-sensitive and easily oxidized; prolonged exposure to light, heat, or air should be avoided to maintain stability and prevent premature polymerization. Keep away from strong bases and incompatible materials.
