Description

4-Hydroxybutyl Acrylate is a bifunctional monomer containing both a polymerizable acrylate group and a reactive hydroxyl group. This unique structure makes it a versatile chemical intermediate for creating polymers with tailored properties, such as enhanced adhesion, flexibility, and crosslinking potential. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to develop high-performance materials.

Application

• UV-Curable Coatings and Inks: A key monomer for formulating fast-curing, low-VOC coatings with excellent flexibility and adhesion to various substrates.
• Acrylic Resin Modification: Used to introduce hydroxyl functionality into acrylic copolymers for improved compatibility, crosslinking, and solvent resistance.
• Adhesives and Sealants: Serves as a building block for pressure-sensitive adhesives (PSAs) and structural adhesives requiring strong bonding and durability.
• Fiber Optic Coatings: Employed in the production of primary and secondary coatings for optical fibers due to its curing efficiency and protective properties.
• Photopolymer Printing Plates: A component in resins for liquid photopolymer printing plates, contributing to precise image reproduction and plate resilience.
• Dental and Medical Polymers: Used in the synthesis of biocompatible polymers for dental composites and other medical device applications.
• Crosslinking Agent: The hydroxyl group allows it to act as a crosslinker in polyurethane and polyester systems, enhancing network density and material performance.

Quality Control

Our 4-Hydroxybutyl Acrylate is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets precise specifications for industrial applications. Certificates of Analysis (COA) documenting these results are provided to guarantee supply consistency and product reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). As the product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening. Keep away from heat, sparks, and incompatible materials such as strong oxidizers and bases.
