Description

3-Butoxy-2-Hydroxypropyl Acrylate is a specialized acrylate monomer featuring both a reactive acrylate group and a hydroxyl group, offering bifunctional reactivity for polymer modification. This compound is valued for its ability to impart flexibility, adhesion, and crosslinking potential to acrylic polymers and coatings. It is primarily needed by formulators in the paints & coatings, adhesives, and UV-curable resin industries seeking to enhance product performance.

Application

• UV-Curable Coatings and Inks: A key monomer for formulating radiation-curable systems, providing fast curing, good adhesion, and improved flexibility.
• Acrylic Resin Modification: Used to copolymerize with other acrylates and methacrylates to introduce pendant hydroxyl groups for subsequent crosslinking.
• Adhesives and Sealants: Enhances the adhesive strength, flexibility, and durability of acrylic-based adhesive formulations.
• Reactive Diluent: Functions as a low-viscosity, reactive component to reduce viscosity in high-solid or solvent-free coating systems.
• Crosslinking Agent: The hydroxyl group allows for reactions with isocyanates, melamines, or epoxy resins to create thermoset polymer networks.
• Specialty Polymers: Employed in the synthesis of specialty acrylic polymers for applications requiring tailored hydrophobicity and weatherability.

Quality Control

Our 3-Butoxy-2-Hydroxypropyl Acrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent polymerization and maintain stability. Keep away from heat, sparks, and open flame.
