Description

2-Hydroxyethyl 5-Norbornene-2-Carboxylate is a specialized bifunctional monomer featuring both a reactive norbornene ring and a hydroxyl-terminated ester group. This unique structure makes it a valuable building block for synthesizing advanced polymers with tailored properties, such as enhanced adhesion, crosslink density, and chemical resistance. It is primarily sought after by R&D chemists and formulators in the production of specialty coatings, adhesives, and high-performance resins.

Application

• Crosslinking Agent: Used to introduce crosslinks into polymer backbones (e.g., acrylics, polyesters) to improve hardness, solvent resistance, and thermal stability in coatings and inks.
• Photopolymer & Resin Precursor: Serves as a key monomer in the synthesis of photoresists, solder masks, and other radiation-curable materials for the electronics industry.
• Adhesive Formulation: Enhances the cohesive strength and durability of structural and pressure-sensitive adhesives.
• Modifier for Specialty Polymers: Incorporated into polymers to modify flexibility, adhesion to substrates, and weatherability.
• Intermediate for Fine Chemicals: Utilized in organic synthesis to create more complex molecules for pharmaceutical and agrochemical research.

Quality Control

Our 2-Hydroxyethyl 5-Norbornene-2-Carboxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality. Keep away from heat, sparks, and open flame.
