Description

9-Octadecenoic Acid, 12-Hydroxy-, (9Z,12R)-, Polymer With 1,3-Diisocyanatomethylbenzene And α-Hydro-ω-Hydroxypoly(Oxy(Methyl-1,2-Ethanediyl)) is a specialized polyurethane prepolymer derived from castor oil (ricinoleic acid) and polyethylene glycol. This compound matters as a high-performance, bio-based building block that imparts flexibility, hydrolytic stability, and excellent adhesion properties to final polymer formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking sustainable and high-quality raw materials.

Application

• High-Performance Coatings: Used as a key component in formulating flexible, durable, and chemical-resistant polyurethane coatings for industrial, automotive, and marine applications.
• Adhesives & Sealants: Serves as a prepolymer in the production of moisture-curing polyurethane adhesives and sealants with strong bonding strength and good weatherability.
• Elastomer Manufacturing: Acts as a soft segment in the synthesis of castable and thermoplastic polyurethane elastomers, providing enhanced flexibility and impact resistance.
• Composite Materials: Utilized as a matrix resin or modifier in polymer composites to improve interfacial adhesion between fibers and the polymer matrix.
• Textile Finishing: Employed in the creation of durable, water-repellent, and soft-hand finishes for technical textiles and fabrics.
• Sustainable Polymer Formulations: A preferred choice for developing "green" polyurethane products due to its renewable, castor oil-derived backbone.

Quality Control

Our production of this polyurethane prepolymer adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance. Key parameters such as isocyanate (NCO) content, viscosity, and hydroxyl value are strictly monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to guarantee compliance with your formulation requirements.

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 hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen blanket) after opening to prevent premature reaction and gelation. Keep away from heat, sparks, and open flame.
