Description

1,4-Butanediol Dimethacrylate is a bifunctional methacrylate monomer characterized by its two reactive methacrylate groups. This compound is a crucial building block in polymer chemistry, serving as a cross-linking agent to enhance the thermal stability, mechanical strength, and chemical resistance of final polymer networks. It is primarily needed by manufacturers in the coatings, adhesives, dental materials, and optical lens industries seeking to formulate high-performance, durable products.

Application

• Cross-linking Agent for Acrylic Polymers: Imparts improved hardness, solvent resistance, and thermal properties to coatings, inks, and adhesives.
• Dental Composite Resins: A key monomer used in restorative materials and dental adhesives for its rapid curing and durable finish.
• Optical Lens Manufacturing: Used in the production of high-refractive-index plastics for eyeglasses and optical components.
• UV-Curable Coatings & Inks: Provides fast cure response and enhanced film properties in radiation-curable formulations.
• Fiber Reinforced Plastics (FRP): Acts as a reactive diluent and cross-linker in unsaturated polyester resins for automotive and construction parts.
• Acrylic Sheet & Casting Resins: Used to modify the properties of cast acrylics, improving impact strength and surface hardness.
• Adhesive & Sealant Formulations: Enhances bond strength and environmental resistance in structural and industrial adhesives.
• Photopolymer Printing Plates: A component in photopolymerizable compositions for flexographic printing.

Quality Control

Our 1,4-Butanediol Dimethacrylate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC and impurity profiling, to ensure it meets precise specifications for purity, color, and acid value. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials such as strong oxidizing agents and bases. To maintain optimal quality and prevent premature polymerization, it is recommended to store under an inert atmosphere if the container is opened frequently.
