Description

1,3-Bis(α-Isocyanatoisopropyl)Benzene is a specialized aromatic diisocyanate monomer, a key building block in the synthesis of high-performance polyurethane materials. Its unique structure, featuring two isocyanate groups on an isopropyl-substituted benzene ring, provides enhanced reactivity and contributes to the final polymer's thermal stability and mechanical properties. This compound is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop advanced polyurethane systems with tailored characteristics.

Application

• Primary monomer for synthesizing specialty polyurethane prepolymers and resins.
• Key raw material in the formulation of high-performance industrial coatings and paints requiring excellent chemical resistance and durability.
• Used in the production of advanced adhesives and sealants for automotive, construction, and aerospace applications.
• Essential component for manufacturing specialized polyurethane elastomers with enhanced thermal and mechanical properties.
• Intermediate in the synthesis of blocked isocyanates used in heat-curable coating systems.
• Research and development of novel polymer materials in academic and industrial R&D laboratories.

Quality Control

Our 1,3-Bis(α-Isocyanatoisopropyl)Benzene is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, isocyanate content, and impurity profile analysis, to meet exacting customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 kept under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent reaction with atmospheric moisture and carbon dioxide, which can lead to polymerization or solid formation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
