Description

1,4-Butanediol Diacrylate is a bifunctional acrylate monomer characterized by its two reactive acrylate groups. This compound matters as a versatile cross-linking agent and building block for creating high-performance polymers with tailored properties. It is needed by manufacturers in the coatings, adhesives, and photopolymer industries seeking to enhance durability, chemical resistance, and cure speed in their formulations.

Application

• UV-Curable Coatings & Inks: A key monomer for formulating fast-curing, scratch-resistant, and glossy surface coatings and printing inks.
• Adhesives & Sealants: Used to produce high-strength, durable structural adhesives and sealants with excellent bonding properties.
• Photopolymer Resins: Serves as a critical component in resins for 3D printing (SLA/DLP), dental materials, and photolithography.
• Fiber Optic Coatings: Imparts protective, flexible, and transparent coatings for optical fibers.
• Acrylic Polymer Modification: Acts as a cross-linker to improve the heat resistance, hardness, and solvent resistance of acrylic polymers.
• Reactive Diluent: Functions to reduce the viscosity of oligomer mixtures while actively participating in the polymerization reaction.

Quality Control

Our 1,4-Butanediol Diacrylate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise specifications and industry standards. Certificates of Analysis (COA) are available upon request to guarantee traceability and compliance for your quality assurance protocols.

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; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality and inhibit premature polymerization. Keep away from heat, sparks, and open flame.
