Description

1,4-Butanediol Dimethylacrylate is a bifunctional monomer featuring two reactive methacrylate groups, making it a versatile crosslinking agent and building block for polymer synthesis. Its primary value lies in its ability to form durable, high-performance polymer networks with enhanced mechanical and chemical resistance properties. This product is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to improve product hardness, crosslink density, and thermal stability.

Application

• UV-Curable Coatings & Inks: A key crosslinker for formulating hard, scratch-resistant, and fast-curing surface coatings and printing inks.
• Dental & Medical Polymers: Used in the production of composite resins, denture bases, and other biomedical materials requiring high strength and biocompatibility.
• Adhesives & Sealants: Imparts improved adhesion, cohesion, and environmental resistance to acrylic-based structural and pressure-sensitive adhesives.
• Fiber Optic Coatings: Employed in coatings for optical fibers to provide protective, flexible, and durable layers.
• Lithographic Printing Plates: Acts as a photopolymerizable component in the manufacture of high-resolution printing plates.
• Engineering Plastics & Composites: Serves as a co-monomer or crosslinker to enhance the thermal and mechanical properties of advanced polymer composites.

Quality Control

Our 1,4-Butanediol Dimethylacrylate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis via techniques such as GC and HPLC, to ensure it meets exacting specifications for polymerization-grade monomers. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee traceability and consistency for your production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°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 under an inert gas such as nitrogen to inhibit premature polymerization.
