Description

Hexanedioic Acid, Polymer With 1,4-Butanediol, 1,2-Ethanediol, 1,1'-Methylenebis[Isocyanatobenzene] And 2,2'-Oxybis[Ethanol], Me Et Ketone Oxime-Blocked is a specialized, blocked polyurethane prepolymer designed for high-performance coating systems. This compound matters as a key reactive intermediate that provides controlled cross-linking, enhancing the durability, chemical resistance, and flexibility of final products. It is primarily needed by formulators in the industrial coatings, adhesives, and sealants sectors seeking to develop one-component systems with extended pot life and superior film properties.

Application

• One-Component (1K) Polyurethane Coatings: Serves as a blocked isocyanate crosslinker that activates upon heating, used in automotive OEM, coil, and industrial maintenance paints.
• High-Performance Adhesives & Sealants: Imparts excellent adhesion, elasticity, and resistance to environmental factors in construction and automotive assembly applications.
• Wire & Cable Enamels: Used in formulating insulating coatings that require thermal stability and mechanical protection.
• Textile & Leather Finishes: Provides durable, flexible, and water-resistant coatings for technical textiles and synthetic leather.
• Corrosion-Resistant Primers: A key component in primers for metal substrates, offering enhanced barrier protection.
• Plastic Coatings: Improves surface hardness and chemical resistance on various plastic components.

Quality Control

Our production of this blocked polyurethane prepolymer adheres to strict quality management systems. Every batch is characterized for critical parameters including blocked isocyanate content, viscosity, solids content, and color to ensure batch-to-batch consistency and performance reliability. Comprehensive Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can lead to premature reaction and gelation. Keep away from heat sources and open flame.
