Description

Castor Oil Polymer With Allyl Alc., Diethylene Glycol, 1,1'-Methylenebis[Isocyanatobenzene], Phthalic Anhydride, Polypropylene Glycol And Styrene CAS NO 244235-41-4 is a specialized, multi-component polymeric resin designed for high-performance applications. This compound matters for its unique combination of chemical resistance, flexibility, and durability derived from its hybrid structure of castor oil derivatives, polyols, and aromatic components. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking advanced material properties.

Application

• High-performance industrial coatings and finishes requiring excellent chemical and moisture resistance.
• Specialty adhesives and sealants for construction, automotive, and aerospace applications.
• Flexible and cast elastomers used in gaskets, rollers, and impact-absorbing components.
• Potting and encapsulation compounds for electrical and electronic components.
• Binder systems for advanced composites and fiber-reinforced plastics.
• Modifier for other polymer systems to enhance toughness, adhesion, and weatherability.

Quality Control

Our Castor Oil Polymer is manufactured under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in viscosity, hydroxyl value, acid value, and solid content, meeting precise customer and application requirements. Certificates of Analysis (COA) documenting all key parameters are available upon request to support your quality assurance protocols.

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 and easily oxidized nature, containers must be kept tightly sealed after opening to minimize exposure to moisture and air. For long-term storage, consider using an inert gas blanket.
