Description

1,3-Diisocyanato-2-Methylcyclohexane is a specialized aliphatic diisocyanate monomer, a key building block in advanced polymer synthesis. Its value lies in its ability to impart superior light stability, chemical resistance, and mechanical properties to final polyurethane and polyurea products. This compound is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking high-performance, weatherable materials.

Application

• High-Performance Polyurethane Coatings: Used in automotive clear coats, industrial maintenance paints, and aerospace coatings where exceptional UV resistance and color retention are critical.
• Light-Stable Elastomers: Serves as a core component in the production of weatherable elastomers for exterior applications, such as seals, gaskets, and rollers.
• Specialty Adhesives & Sealants: Formulated into premium-grade adhesives and sealants for construction, marine, and transportation that require durability against environmental exposure.
• Polyurea Spray Linings: A key raw material for fast-curing, chemical-resistant polyurea linings used in tank and pipe protection, as well as truck bed liners.
• Advanced Composite Materials: Employed in resin formulations for composites that demand a balance of toughness, flexibility, and resistance to yellowing.
• Crosslinking Agent: Acts as an effective crosslinker for hydroxyl-functional polymers, enhancing their thermal and chemical stability.

Quality Control

Our production of 1,3-Diisocyanato-2-Methylcyclohexane adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Every lot is analyzed using advanced techniques including GC, HPLC, and titration to confirm key parameters such as isocyanate content, hydrolyzable chloride, and total chlorine. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container under a dry, inert atmosphere (e.g., nitrogen), protected from light. Store in a cool, well-ventilated area at temperatures recommended for isocyanates (typically 15-25°C). Due to its highly volatile and reactive nature, keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, amines, and strong bases. Containers must be kept tightly sealed when not in use to prevent moisture absorption and polymerization.
