Description

Propoxylate Neopentylene Glycol Diacrylate is a specialized difunctional acrylate monomer, also known by its CAS number 84170-74-1. This compound is valued for its ability to impart flexibility, toughness, and enhanced crosslinking density to polymer networks, making it a critical performance additive. It is primarily sought after by formulators in the UV/EB-curable coatings, inks, adhesives, and advanced resin industries.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker for wood, plastic, and metal coatings, offering fast cure speeds and improved film flexibility.
• Adhesives & Sealants: Used to enhance the adhesion, cohesion, and durability of pressure-sensitive and structural adhesives.
• Photopolymer Resins: A crucial component in formulations for 3D printing (SLA/DLP), providing low viscosity and excellent mechanical properties in printed parts.
• Fiber Optic Coatings: Imparts protective, flexible, and durable secondary coatings to optical fibers.
• Overprint Varnishes: Used to create high-gloss, scratch-resistant, and flexible topcoats for packaging materials.
• Dental Composites: Employed in light-curable restorative materials to achieve optimal strength and wear resistance.
• Electronics Encapsulation: Provides protective, insulating, and durable potting or encapsulating materials for electronic components.

Quality Control

Our Propoxylate Neopentylene Glycol Diacrylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, color, and viscosity is provided with every shipment to guarantee it meets your formulation specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C under an inert atmosphere (e.g., nitrogen) to prevent oxidation and premature polymerization. Keep away from heat, sparks, and open flame. For long-term storage, refrigeration may be recommended; please consult the specific technical data sheet.
