Description

Neopentyl Glycol Ethoxylate (1 Eo/Oh) Diacrylate, Average Mn Ca. 300 is a specialized, low-viscosity difunctional acrylate monomer. This compound is engineered to provide a unique balance of reactivity and flexibility, making it a critical component in formulations requiring fast cure speeds and enhanced polymer properties. It is primarily sought by manufacturers in the UV/EB-curable coatings, inks, adhesives, and advanced resin sectors for its ability to improve crosslink density and final material performance.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker for wood, plastic, and metal coatings, offering excellent cure response and hardness.
• Electronics & Photoresists: Used in the formulation of solder masks and photo-imageable materials due to its precise reactivity and film-forming characteristics.
• Adhesives & Sealants: Enhances the adhesion and durability of acrylic-based pressure-sensitive and structural adhesives.
• Dental & Biomedical Composites: Serves as a monomer in light-curable composites, providing low shrinkage and good mechanical strength.
• 3D Printing Resins: A valuable component in stereolithography (SLA) and digital light processing (DLP) resins, contributing to high-resolution prints with tailored flexibility.
• Fiber Optic Coatings: Used in primary and secondary coatings to protect optical fibers, leveraging its fast curing and protective properties.

Quality Control

Our Neopentyl Glycol Ethoxylate Diacrylate is manufactured under a stringent quality management system. Each batch is analyzed to ensure consistent purity, functionality, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, acid value, color, and inhibitor content are provided to guarantee compliance with your technical requirements and support your quality assurance protocols.

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 and easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and prevent premature polymerization. Keep away from heat, sparks, and open flame.
