Description

Hydroxypropyl Acrylate is a versatile and reactive acrylate monomer featuring a hydroxyl functional group. This dual functionality is critical for creating polymers with enhanced adhesion, crosslinking capability, and chemical resistance. It is an essential raw material for formulators and manufacturers in the coatings, adhesives, and advanced materials sectors seeking to improve product performance.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, offering fast cure times and excellent surface adhesion.
• Adhesives & Sealants: Used to produce pressure-sensitive adhesives (PSAs) and structural adhesives with improved flexibility and bond strength.
• Acrylic Resin Modification: Serves as a co-monomer to introduce hydroxyl groups into acrylic copolymers for subsequent crosslinking with isocyanates or melamines.
• Fiber Optic Coatings: Employed in the production of primary and secondary coatings for optical fibers due to its reactivity and protective properties.
• Photoresists & Photopolymers: Utilized in electronics and printing plate manufacturing for its precise reactivity under UV light.
• Textile & Leather Finishes: Imparts durable, water-resistant, and flexible finishes to fabrics and leather goods.

Quality Control

Our Hydroxypropyl Acrylate is manufactured under a stringent quality management system. Every batch is analyzed to ensure it meets precise specifications for purity, color, and inhibitor content. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with each shipment to guarantee consistency and support your quality assurance protocols.

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). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., nitrogen) in the headspace of partially used containers is recommended to prevent premature polymerization. Keep away from heat, sparks, and open flame.
