Description

1,3-Butylenedimethacrylate is a bifunctional methacrylate monomer characterized by its two reactive methacrylic groups. This compound is a crucial cross-linking agent and building block in the synthesis of high-performance polymers, valued for its ability to enhance hardness, chemical resistance, and thermal stability in the final material. It is primarily sought by manufacturers in the coatings, adhesives, dental materials, and optical lens industries for formulating durable, cross-linked networks.

Application

• Cross-linking Agent for Polymers: Used to create three-dimensional networks in acrylic and methacrylic resins, improving their mechanical strength and solvent resistance.
• Dental Composites & Restoratives: A key monomer in dental filling materials and crown & bridge resins, contributing to durability and wear resistance.
• Optical Lens Manufacturing: Employed in the production of high-index optical lenses and hard coatings, where clarity and scratch resistance are paramount.
• Adhesives & Sealants: Enhances the performance of anaerobic and structural adhesives by promoting rapid curing and strong bond formation.
• UV-Curable Coatings & Inks: Serves as a reactive diluent and cross-linker in formulations that cure under UV light, offering fast processing and low VOC emissions.
• Fiber Reinforced Plastics (FRP): Used in gel coats and laminating resins for marine and automotive applications to improve surface finish and environmental resistance.

Quality Control

Our 1,3-Butylenedimethacrylate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee compliance with your formulation requirements.

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). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and organic solvents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
