Description

Carbonic acid, diphenyl ester, polymer with 1,6-hexanediol, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane and 4,4'-methylenebis[cyclohexanamine], Me Et ketone oxime-blocked is a specialized blocked polyurethane prepolymer designed for high-performance applications. This compound matters as a key latent curing agent, offering excellent shelf stability and controlled reactivity upon heating for precise formulation. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking durable, chemically resistant, and flexible end products.

Application

• High-Performance Industrial Coatings: Used as a crosslinker in heat-cured polyurethane coatings for automotive, aerospace, and heavy-duty equipment, providing excellent chemical and abrasion resistance.
• Adhesives and Sealants: Serves as a latent curing component in one-component (1K) polyurethane systems, ensuring long pot life and strong, flexible bonds upon activation.
• Elastomer Production: Employed in the manufacture of castable and thermoplastic polyurethane elastomers requiring tailored hardness, elasticity, and dynamic properties.
• Wire and Cable Insulation: Utilized in formulating insulating and jacketing materials that demand thermal stability and environmental protection.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced composites for the marine, construction, and sporting goods sectors.
• Textile and Leather Finishes: Incorporated into coatings and finishes to impart water repellency, durability, and a soft hand feel.

Quality Control

Our blocked polyurethane prepolymers undergo rigorous quality testing to ensure batch-to-batch consistency and performance reliability. Production adheres to strict in-process controls, and each lot is characterized for critical parameters such as blocked isocyanate content, viscosity, and deblocking temperature. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

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 material is moisture-sensitive (hygroscopic); keep the container tightly sealed when not in use to prevent exposure to atmospheric moisture, which can lead to premature reaction and gelation.
