Description

2-Propenoic Acid, 2-Hydroxy-, Ethyl Ester (9Ci) is a specialized acrylic ester derivative, also known as ethyl 2-hydroxyacrylate, valued for its bifunctional reactivity. This compound is essential for synthesizing advanced polymers and fine chemicals where the introduction of both a polymerizable vinyl group and a reactive hydroxyl group is required. It is a critical intermediate for R&D chemists and production engineers in the polymer, coatings, and specialty chemical industries.

Application

• Polymer & Resin Synthesis: A key monomer for producing hydroxyl-functional acrylic copolymers used in high-performance coatings, adhesives, and sealants.
• UV-Curable Systems: Used in the formulation of oligomers and prepolymers for UV-curable inks, coatings, and 3D printing resins due to its crosslinkable groups.
• Chemical Intermediate: Serves as a versatile building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals.
• Surface Modifiers: Imparts improved adhesion, wettability, and durability when incorporated into surface treatment formulations for metals, plastics, and composites.
• Hydrogel Production: Utilized in the creation of hydrophilic and biocompatible polymer networks for medical and cosmetic applications.
