Description

Soybean Oil, Maleated is a chemically modified vegetable oil derivative, produced via the maleation of soybean oil to introduce reactive maleic anhydride moieties. This modification imparts enhanced functionality, making it a versatile intermediate for polymer synthesis and surface modification. It is primarily utilized in the formulation of alkyd resins, plasticizers, and as a reactive diluent or crosslinking agent in coatings, adhesives, and composite materials.

Application

• Production of alkyd resins for industrial and architectural coatings.
• Acting as a reactive plasticizer or crosslinker in polymer systems, including polyesters and epoxies.
• Formulation of adhesives and sealants to improve flexibility and adhesion.
• Manufacture of composite materials and fiber-reinforced plastics.
• Use as a surface treatment agent or corrosion inhibitor.
• Intermediate in the synthesis of specialty surfactants and lubricant additives.
• Potential component in bio-based polymer research and development.

Quality Control

Our Soybean Oil, Maleated is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency in parameters such as acid value, saponification value, viscosity, and degree of maleation. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) to minimize oxidation and moisture absorption.
