Description

1,3-Butanediol Diacrylate is a high-purity, bifunctional acrylate monomer characterized by its excellent reactivity and crosslinking capability. This compound is a critical building block in the formulation of advanced polymers, offering enhanced properties such as improved hardness, chemical resistance, and durability in the final cured material. It is essential for manufacturers in the coatings, adhesives, and photopolymer industries seeking to develop high-performance, radiation-curable products.

Application

• UV/EB Curable Coatings & Inks: A key reactive diluent and crosslinker for formulations requiring fast cure speeds, high gloss, and superior surface hardness.
• Adhesives & Sealants: Used to enhance the bonding strength, flexibility, and environmental resistance of acrylic-based adhesive systems.
• Photopolymer Resins: Serves as a fundamental component in resins for 3D printing (stereolithography - SLA) and photopolymer plates, contributing to precise detail and stability.
• Fiber Optic Coatings: Employed in coatings that protect optical fibers, providing necessary durability and signal transmission properties.
• Dental & Medical Composites: Used in light-curable composites for restorative dentistry and certain medical device applications.
• Printing Plates & Electronics: A component in photoresists and solder masks for printed circuit boards (PCBs) and flexible electronics.

Quality Control

Our 1,3-Butanediol Diacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) and infrared spectroscopy (IR), to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing assay, identity, and impurity profiles are provided with each shipment to guarantee compliance with your technical requirements.

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