Description

Acrylicacid,3-Hydroxypropylester is a versatile bifunctional monomer containing both an acrylic ester group and a hydroxyl group. This unique structure makes it a critical building block for synthesizing polymers with tailored properties, such as enhanced adhesion, crosslinking capability, and flexibility. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to develop high-performance, functional materials.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker, contributing to fast curing, high gloss, and chemical resistance in industrial and graphic arts applications.
• Adhesives & Sealants: Used to formulate pressure-sensitive adhesives (PSAs) and structural adhesives with improved tack, peel strength, and environmental durability.
• Acrylic Resin Modification: Imparts hydroxyl functionality for crosslinking with isocyanates or melamine resins, enhancing the hardness and weatherability of automotive and industrial coatings.
• Hydrogel Synthesis: A key monomer for creating hydrophilic polymers used in biomedical applications, contact lenses, and wound dressings.
• Fiber Reactive Sizing Agents: Improves the binding and performance of sizing agents on synthetic and natural fibers in the textile industry.
• Photopolymer Resins: A component in resins for 3D printing (stereolithography) and photoresists, offering precise polymerization control.

Quality Control

Our Acrylicacid,3-Hydroxypropylester is produced under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with every shipment to guarantee supply consistency and reliability for your critical formulations.

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). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) and away from heat, sparks, and open flames. Keep container tightly sealed when not in use to minimize evaporation and prevent moisture absorption.
