Description

Bisphenol A Epoxy Diacrylate is a high-performance, difunctional acrylate monomer derived from bisphenol A epoxy resin. This compound is valued for its ability to impart excellent chemical resistance, hardness, and thermal stability to cured polymer networks. It is a critical raw material for formulators and manufacturers in the coatings, inks, adhesives, and advanced composites industries seeking to enhance product durability and performance.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, as well as graphic arts and packaging inks, providing fast cure speeds and superior surface properties.
• Adhesives & Sealants: Used in radiation-curable structural and pressure-sensitive adhesives (PSAs) to achieve high bond strength and environmental resistance.
• Fiber Reinforced Composites: Serves as a matrix resin in glass or carbon fiber composites for automotive, aerospace, and marine applications, offering high modulus and toughness.
• 3D Printing Resins: Employed in stereolithography (SLA) and other photopolymerization-based additive manufacturing processes to create durable, high-resolution parts.
• Electronic Encapsulants & Potting Compounds: Provides protective, insulating layers for electronic components due to its good dielectric properties and moisture resistance.
• Dental & Medical Materials: Utilized in the formulation of light-curable dental restoratives and biocompatible device coatings.

Quality Control

Our Bisphenol A Epoxy Diacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters monitored include acrylate equivalent weight, viscosity, color, acid value, and residual monomer content. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and product integrity.

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). Keep away from heat, sparks, and open flame. Incompatible with strong acids and strong oxidizing agents. For long-term storage, consider under an inert atmosphere to minimize premature polymerization.
