Description

2-Hydroxybutyl Methacrylate is a monofunctional methacrylate monomer containing both a polymerizable methacrylic group and a reactive hydroxyl group. This bifunctional nature makes it a versatile chemical intermediate for introducing cross-linking sites and enhancing adhesion properties in polymer systems. It is primarily utilized in the production of specialty coatings, adhesives, and photopolymer resins where improved flexibility, weatherability, and chemical resistance are required.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and cross-linking agent in formulations for wood, plastic, and metal coatings, offering fast cure speeds and excellent surface adhesion.
• Acrylic Resin Modification: Used to copolymerize with other acrylates and methacrylates to produce resins with tailored hydroxyl values for improved compatibility with isocyanates in polyurethane systems.
• Adhesives & Sealants: Imparts enhanced flexibility and toughness to acrylic-based pressure-sensitive adhesives (PSAs) and structural adhesives.
• Photopolymer Printing Plates: Serves as a crucial monomer in liquid photopolymer resin compositions for flexographic and letterpress printing plates, contributing to desired elastomeric properties.
• Dental & Medical Materials: Employed in the synthesis of biocompatible polymers for dental composites and bone cements due to its ability to form stable, cross-linked networks.
• Fiber Optic Coatings: Used in coatings for optical fibers to provide protective, flexible layers with good environmental resistance.

Quality Control

Our 2-Hydroxybutyl Methacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile determination via GC and HPLC, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency for your production processes.

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 (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, consider under an inert gas such as nitrogen to inhibit polymerization.
