Description

But-2-Enylene Bisacrylate is a high-purity, bifunctional acrylate monomer characterized by its reactive double bonds. This compound is essential for creating highly cross-linked polymer networks, offering superior hardness, chemical resistance, and thermal stability to the final material. It is a critical raw material for manufacturers in the coatings, advanced adhesives, photopolymer resins, and specialty plastics industries seeking to enhance product performance.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for formulating hard, scratch-resistant, and fast-curing surface coatings and printing inks.
• Photopolymer Resins: Used in stereolithography (SLA) and other 3D printing resins to improve resolution and mechanical properties of printed parts.
• Adhesives & Sealants: Imparts strong adhesion and durability in anaerobic, acrylic, and structural adhesive formulations.
• Dental & Medical Composites: Serves as a co-monomer in restorative materials and biocompatible polymer matrices.
• Fiber Optic Coatings: Contributes to the protective primary and secondary coatings due to its rapid cure and protective qualities.
• Electronics Encapsulation: Used in potting compounds and conformal coatings to protect sensitive electronic components.
• Lithographic Plates: A component in light-sensitive polymers for printing plate production.

Quality Control

Our But-2-Enylene Bisacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis via HPLC and GC, to ensure it meets stringent specifications. A Certificate of Analysis (COA) documenting identity, purity, and physical properties is provided with each shipment to guarantee traceability and compliance.

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 light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert gas such as nitrogen.
