Description

2,2-Bis(But-3-Enoyloxymethyl)Butyl But-3-Enoate is a specialized multifunctional acrylate ester monomer containing multiple polymerizable but-3-enoyl (vinyl acrylate) groups. This compound matters for its ability to form highly cross-linked polymer networks, imparting exceptional hardness, chemical resistance, and thermal stability to final materials. It is primarily needed by R&D chemists and formulators in the advanced polymer, specialty coatings, and photoresist industries seeking to develop high-performance thermoset resins.

Application

• Cross-linking Agent for High-Performance Coatings: Used to formulate durable, scratch-resistant, and chemically inert industrial, automotive, and optical coatings.
• Photopolymer & Photoresist Formulation: Serves as a key monomer in UV-curable inks, adhesives, and photoresists for electronics and 3D printing due to its rapid curing properties.
• Dental & Biomedical Composites: Employed in the synthesis of biocompatible, high-strength polymer matrices for dental restorative materials and bone cements.
• Adhesive & Sealant Chemistry: Enhances the bond strength, thermal stability, and environmental resistance of structural adhesives and specialty sealants.
• Fiber-Reinforced Plastic (FRP) Manufacturing: Acts as a reactive diluent and cross-linker in vinyl ester and unsaturated polyester resins for composites.
• Specialty Polymer Synthesis: Utilized as a building block for creating custom dendrimers, hyperbranched polymers, and other advanced macromolecular architectures.

Quality Control

Our 2,2-Bis(But-3-Enoyloxymethyl)Butyl But-3-Enoate undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. We employ advanced analytical techniques including HPLC, GC, and NMR to verify purity, identity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C/59-77°F). Due to its polymerizable nature and sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and initiators.
