Description

2,3-Epoxypropyl Propionate is a versatile epoxy-functional monomer and reactive diluent. This compound is valued for its ability to introduce cross-linking sites and modify the properties of polymer systems, enhancing flexibility and chemical resistance. It is primarily utilized in the production of specialty coatings, adhesives, and as a key intermediate in the synthesis of more complex chemical entities for the pharmaceutical and agrochemical industries.

Application

• Reactive Diluent in Epoxy Resins: Used to reduce viscosity and improve workability of epoxy formulations for coatings and composites.
• Cross-linking Agent: Imparts chemical resistance and durability in high-performance surface coatings and paints.
• Chemical Intermediate: Serves as a key building block in the synthesis of pharmaceutical actives and agrochemicals.
• Adhesive Formulations: Enhances adhesion and flexibility in structural and specialty adhesive systems.
• UV-Curable Systems: A functional monomer in formulations for inks, coatings, and 3D printing resins that cure under UV light.
• Modifier for Polymers: Used to graft epoxy functionality onto polymer chains to alter thermal and mechanical properties.

Quality Control

Our 2,3-Epoxypropyl Propionate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas blanket (e.g., nitrogen) and keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (36-46°F) for extended shelf life.
