Description

Propanol, oxybis-, polymer with 1,3-diisocyanatomethylbenzene Toluene diisocyanate, dipropylene glycol polymer propanol, oxybis-, polymer with1,3-diisocyanatomethylbenzene CAS NO 9072-93-9 is a specialized polyurethane prepolymer based on toluene diisocyanate (TDI) and dipropylene glycol. This high-performance chemical intermediate is valued for its ability to impart excellent durability, flexibility, and chemical resistance to final polymer formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings & Paints: Used as a key resin component in two-component polyurethane coatings for industrial maintenance, automotive refinish, and marine applications, providing excellent gloss retention and weather resistance.
• Adhesives & Sealants: Serves as a prepolymer in the formulation of flexible and structural polyurethane adhesives and sealants for construction, automotive assembly, and footwear manufacturing.
• Elastomers & Castable Urethanes: A critical building block for producing polyurethane elastomers with tailored hardness, tensile strength, and abrasion resistance for wheels, rollers, and industrial parts.
• Binder Systems: Employed in composite materials and foundry sand binders to improve binding strength and thermal stability.
• Waterproofing Membranes: Formulated into liquid-applied waterproofing and roofing systems that cure to form a seamless, durable protective layer.
• Flexible Foams (Modified): Can be used to modify the properties of flexible polyurethane foams, enhancing load-bearing and comfort characteristics.

Quality Control

Our TDI-based prepolymers are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through parameters including % NCO content, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Our production adheres to ISO 9001 quality management principles, and we support our global customers with comprehensive regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature curing and viscosity increase. Keep away from heat, sparks, and open flame. Keep container tightly sealed under a dry, inert atmosphere (e.g., nitrogen blanket) after initial opening.
