Description

1-Isocyanato-2-(3-isocyanatopropyl)cyclohexane is a specialized aliphatic diisocyanate monomer featuring a cyclohexane backbone. This compound is valued for its ability to impart enhanced chemical resistance, flexibility, and weatherability to polyurethane systems. It is primarily sought after by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for high-performance applications.

Application

• High-Performance Polyurethane Coatings: Used as a crosslinker in automotive clear coats, industrial maintenance paints, and aerospace coatings for superior durability and UV resistance.
• Specialty Adhesives & Sealants: A key component in formulating adhesives and sealants that require excellent flexibility, adhesion, and resistance to harsh environments.
• Elastomers and Castables: Serves as a building block for polyurethane elastomers used in rollers, gaskets, and industrial parts demanding a balance of toughness and elasticity.
• Weatherable Resins: Incorporated into resin systems for outdoor applications where resistance to yellowing and degradation from sunlight is critical.
• Chemical Modification Intermediate: Used in organic synthesis to introduce isocyanate functionality for further chemical reactions and polymer modifications.

Quality Control

Our production of 1-Isocyanato-2-(3-isocyanatopropyl)cyclohexane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, isocyanate content, and impurity profile analysis, to ensure consistency and performance. Certificates of Analysis (COA) documenting purity and key specifications are provided with each shipment to support your quality assurance processes.

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 material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
