Description

4-Vinylcyclohexene Dioxide is a high-purity, highly reactive cycloaliphatic epoxide monomer. This compound matters as a critical building block in advanced polymer chemistry, enabling the synthesis of materials with superior thermal stability, chemical resistance, and low dielectric constants. It is primarily needed by manufacturers in the electronics, aerospace, and specialty coatings industries for creating high-performance resins, adhesives, and composite materials.

Application

• Epoxy Resin Formulation: A key monomer for producing cycloaliphatic epoxy resins with excellent weatherability and electrical properties.
• Electronic Encapsulants & Underfills: Used in semiconductor packaging and printed circuit boards (PCBs) due to its low viscosity and high purity.
• Advanced Composite Materials: Serves as a cross-linking agent in fiber-reinforced plastics for aerospace and automotive components.
• Specialty Coatings & Adhesives: Imparts enhanced chemical and UV resistance to industrial and protective coatings, as well as high-strength adhesives.
• Chemical Intermediate: Utilized in organic synthesis for pharmaceuticals and agrochemicals.
• Diluent for Epoxy Systems: Acts as a reactive diluent to modify the viscosity and handling characteristics of standard epoxy formulations.

Quality Control

Our 4-Vinylcyclohexene Dioxide is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) and Karl Fischer titration, to ensure it meets precise purity and moisture specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each 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 highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
