Description

Oxiranecarboxylic Acid, 2-Methyl-, 2-Propenyl Ester (9Ci) is a specialized glycidyl ester derivative, valued for its reactive oxirane (epoxide) and acrylate functionalities. This dual functionality makes it a critical building block in advanced polymer synthesis, enabling the creation of materials with tailored cross-linking density, adhesion, and chemical resistance. It is primarily sought by R&D and production teams in the coatings, adhesives, and specialty polymer industries for formulating high-performance resins and reactive diluents.

Application

• Reactive Diluent & Cross-Linker: Used in radiation-curable (UV/EB) coatings, inks, and adhesives to modify viscosity and enhance final film properties.
• Epoxy Resin Modifier: Serves as a co-monomer or additive in epoxy resin systems to improve flexibility, adhesion, and weatherability.
• Acrylic Polymer Synthesis: Acts as a functional monomer for introducing epoxy groups into acrylic copolymer chains for automotive and industrial coatings.
• Fiber Reinforced Composites: Employed in the matrix resin formulations for composites requiring high strength-to-weight ratios and chemical stability.
• Electronic Encapsulants & Potting Compounds: Used in formulations that protect sensitive electronic components, offering excellent insulation and environmental resistance.
• Adhesive Primer & Coupling Agent: Enhances the bond strength between dissimilar substrates, such as metals, plastics, and glass.

Quality Control

Our production of Oxiranecarboxylic Acid, 2-Methyl-, 2-Propenyl Ester adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, purity verification, and impurity profiling, to ensure consistency and reliability for your formulations. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after initial use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
