Description

2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediyl Diacrylate is a high-purity, multi-functional acrylate monomer essential for creating advanced polymer networks. Its trifunctional structure provides excellent cross-linking density, significantly enhancing the hardness, chemical resistance, and thermal stability of cured materials. This product is critical for formulators and manufacturers in the coatings, adhesives, and advanced resin industries seeking to develop high-performance, durable end-products.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for formulating high-gloss, scratch-resistant, and fast-curing industrial and graphic arts coatings.
• Adhesives & Sealants: Used to enhance the bond strength, flexibility, and environmental durability of acrylic-based structural and pressure-sensitive adhesives.
• Photoresists & Electronics: Serves as a critical monomer in the production of photopolymerizable resins for printed circuit boards (PCBs) and semiconductor encapsulation materials.
• Dental & Medical Composites: Employed in light-curable composites and restorative materials due to its biocompatibility and ability to form rigid, stable polymer matrices.
• Fiber Optic Coatings: Provides protective, cross-linked coatings with excellent clarity and resistance to moisture and mechanical stress for optical fibers.
• 3D Printing Resins: A vital component in stereolithography (SLA) and digital light processing (DLP) resins, contributing to high-resolution, tough printed parts.

Quality Control

Our 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediyl 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 for high-performance applications. Certificates of Analysis (COA) are provided with each shipment to guarantee traceability, consistency, and compliance with relevant industry standards.

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, open flames, and incompatible materials such as strong acids and organic solvents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
