Description

cis-9:10,12:13-Diepoxystearic Acidmethyl Ester is a specialized epoxidized fatty acid ester derived from stearic acid, serving as a versatile chemical intermediate. Its value lies in its reactive epoxide groups, which enable it to function as a cross-linking agent, plasticizer, or stabilizer in polymer formulations. This compound is primarily needed by manufacturers in the polymer, coatings, and specialty chemical industries seeking to modify material properties such as flexibility, adhesion, and thermal stability.

Application

• As a reactive diluent and cross-linking agent in epoxy resin systems for coatings and composites.
• As a plasticizer and stabilizer precursor in the production of flexible PVC and other polymers.
• As a chemical intermediate for synthesizing polyols, lubricant additives, and surfactants.
• In research and development for creating novel bio-based polymers and materials.
• As a component in adhesive and sealant formulations to enhance performance characteristics.

Quality Control

Our cis-9:10,12:13-Diepoxystearic Acidmethyl Ester is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing key parameters such as assay, epoxide content, and impurity profiles are available upon request to support your quality assurance processes.

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). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and prevent degradation.
