Description

1,5-Pentanediol Diacrylate is a bifunctional acrylate monomer characterized by its two reactive acrylate groups and a flexible pentamethylene spacer. This compound is valued for its ability to form highly cross-linked polymer networks, imparting durability, chemical resistance, and tailored mechanical properties to final products. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance through precise molecular design.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for producing fast-curing, high-gloss, and abrasion-resistant surface finishes for wood, plastics, and metals.
• Adhesives & Sealants: Used to formulate high-strength, flexible structural adhesives with excellent adhesion to diverse substrates.
• Photopolymer Resins: Serves as a critical component in resins for 3D printing (SLA/DLP) and photopolymer plates, enabling high-resolution and tough printed parts.
• Fiber Optic Coatings: Contributes to the production of protective, flexible secondary coatings that safeguard optical fibers.
• Dental & Medical Composites: Employed in light-curable composites for dental restorations and other biomedical applications requiring biocompatibility and strength.
• Electronics Encapsulation: Used in potting compounds and encapsulants to protect sensitive electronic components, offering good electrical properties and environmental resistance.

Quality Control

Our 1,5-Pentanediol Diacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise specifications and consistent performance for your formulations. A Certificate of Analysis (COA) detailing all quality parameters is provided with each shipment.

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