Description

Tolyl Isocyanate CAS NO 114772-51-1 is a specialized aromatic isocyanate monomer, a key building block in the synthesis of advanced polymers and fine chemicals. Its primary value lies in its high reactivity, enabling the formation of durable polyurethane and polyurea linkages, which are essential for creating materials with superior mechanical and chemical resistance properties. This product is critically needed by manufacturers in the polyurethane, coatings, adhesives, and specialty chemical industries for developing high-performance elastomers, sealants, and advanced resin systems.

Application

• Polyurethane Synthesis: A core monomer for producing high-performance polyurethane elastomers, foams, and coatings with excellent abrasion and chemical resistance.
• Adhesives & Sealants: Used in formulating industrial-grade adhesives and sealants that require strong bonding and flexibility under harsh environmental conditions.
• Specialty Coatings: Serves as a key component in advanced two-component (2K) coatings for automotive, industrial, and marine applications, providing enhanced durability and gloss retention.
• Chemical Intermediate: Acts as a versatile building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals, facilitating the introduction of the isocyanate functional group.
• Cross-linking Agent: Employed to cross-link polymers, improving their thermal stability, tensile strength, and solvent resistance in composite materials.
• Rubber Modification: Used to modify synthetic rubbers, enhancing their properties for demanding applications in gaskets, hoses, and vibration dampeners.

Quality Control

Our Tolyl Isocyanate is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to verify identity and assay. A comprehensive Certificate of Analysis (COA), detailing purity and impurity profiles, is provided with every shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
