Description

2,2-Bis(Hydroxymethyl)Butyl Acrylate is a specialty acrylate monomer featuring a unique branched structure with dual hydroxyl functionality. This chemical structure is critical for its role as a versatile building block in advanced polymer synthesis, enabling the introduction of cross-linking sites and enhanced adhesion properties. It is primarily sought after by formulators and researchers in the coatings, adhesives, and radiation-curable resin industries who require monomers that impart toughness, chemical resistance, and improved substrate bonding to their final products.

Application

• UV/EB Curable Coatings and Inks: Serves as a reactive diluent and cross-linking agent to formulate high-performance, low-VOC coatings with excellent adhesion and flexibility.
• Adhesives and Sealants: Used to synthesize acrylic polymers that provide strong bonding strength and durability for industrial and construction applications.
• Acrylic Resin Modification: Incorporated into polymer backbones to introduce hydroxyl groups for subsequent reactions with isocyanates or melamines, enhancing film properties.
• Dental and Biomedical Materials: Acts as a key monomer in the production of biocompatible polymers for restorative and prosthetic applications.
• Fiber Optic Coatings: Utilized in radiation-curable coatings that protect optical fibers due to its fast cure and protective properties.
• Printing Plate Resins: A component in photopolymerizable resins for flexographic and letterpress printing plates.

Quality Control

Our 2,2-Bis(Hydroxymethyl)Butyl Acrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing purity, color, acid value, and moisture content is provided with each shipment to guarantee traceability and compliance.

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). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability and to minimize polymerization risk. Keep away from heat, sparks, and open flame.
