Description

Fatty acids, castor-oil, Me esters, reaction products with 1,3-bis(1-isocyanato-1-methylethyl)benzene, polyethylene glycol, propylene glycol and trimethylolpropane is a specialized polyurethane prepolymer or polyol derivative, identified by CAS No. 211450-52-1. This advanced chemical intermediate is engineered to impart unique flexibility, hydrophilicity, and adhesion properties to polymer systems. It is a critical raw material for formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Polyurethane Coatings: Used as a reactive polyol component to formulate flexible, impact-resistant, and weather-durable coatings for automotive, industrial, and marine applications.
• Adhesives and Sealants: Serves as a key ingredient in moisture-curing and two-component polyurethane adhesives, providing excellent substrate wetting and bond strength on challenging surfaces.
• Elastomer Manufacturing: Incorporated into castable and thermoplastic polyurethane elastomers (TPU) to modify hardness, elongation, and hydrolytic stability.
• Textile and Leather Finishes: Utilized in the synthesis of polyurethane dispersions (PUDs) for flexible, breathable, and soft-hand finishes on fabrics and synthetic leather.
• Composite Materials: Acts as a compatibilizer and toughening agent in polymer composites, improving interfacial adhesion between matrices and fillers.
• Specialty Additives: Functions as a base for producing surfactants or rheology modifiers due to its hybrid hydrophobic/hydrophilic structure derived from castor oil and polyethylene glycol.

Quality Control

Our production of this advanced polyurethane intermediate adheres to strict quality management systems, ensuring batch-to-batch consistency for demanding industrial applications. Key parameters such as isocyanate (NCO) content, hydroxyl value, viscosity, and moisture content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance 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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat, sparks, and open flame.
