Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol (3:1), 2-Propenoate is a specialized reactive oligomer designed for high-performance polymer synthesis. This compound matters for its unique combination of polyether backbone functionality and a polymerizable acrylate end-group, enabling precise control over cross-linking density and final material properties. It is primarily needed by formulators and manufacturers in the coatings, adhesives, and advanced composites industries seeking to enhance durability, flexibility, and chemical resistance.

Application

• UV-Curable Coatings & Inks: Acts as a key reactive diluent and oligomer to formulate fast-curing, high-gloss, and scratch-resistant surface finishes.
• Advanced Adhesives & Sealants: Used to synthesize polyurethane prepolymers and acrylic hybrids, improving adhesion strength and environmental stability.
• Fiber-Reinforced Composites: Serves as a matrix resin component for aerospace and automotive parts, contributing to lightweight and high-strength materials.
• 3D Printing Resins: A critical ingredient in stereolithography (SLA) and digital light processing (DLP) resins, offering excellent resolution and mechanical properties.
• Electronic Encapsulants: Provides protective, insulating layers for sensitive electronic components due to its potential for tailored hardness and thermal stability.
• Industrial & Protective Coatings: Formulated into corrosion-resistant and chemical-resistant coatings for metal, concrete, and plastic substrates.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Ether With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol (3:1), 2-Propenoate undergoes rigorous quality testing to ensure compliance with industry standards. We implement strict in-process controls and final batch analysis, including monitoring of acrylate functionality, residual monomers, and viscosity. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request to 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°C and 25°C (59°F and 77°F). This product is easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider blanketing with an inert gas such as nitrogen to prevent polymerization and maintain product integrity.
