Description

Hexanedioic Acid, Polymer With 1,2-Ethanediol, 1,6-Hexanediol And 1,1'-Methylenebis[4-Isocyanatobenzene] CAS NO 36906-15-7 is a high-performance polyurethane prepolymer or resin derived from adipic acid, a blend of diols, and methylene diphenyl diisocyanate (MDI). This engineered polymer is valued for its versatile mechanical properties, including excellent flexibility, toughness, and adhesion, making it a critical raw material for formulating advanced coatings, adhesives, and elastomers. It is essential for manufacturers in the automotive, construction, and industrial coatings sectors seeking durable, high-performance polymeric materials.

Application

• High-Performance Coatings and Paints: Used as a binder in industrial, automotive, and protective coatings for enhanced durability, chemical resistance, and gloss.
• Adhesives and Sealants: Serves as a key component in formulating structural, laminating, and assembly adhesives with strong bonding strength and flexibility.
• Elastomers and Castable Urethanes: Employed in the production of flexible parts, rollers, gaskets, and wheels requiring abrasion resistance and resilience.
• Textile and Leather Finishing: Used in coatings and finishes to provide water resistance, durability, and a soft hand feel.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics and other composite systems.
• Industrial and Construction Sealants: Formulated into flexible, weather-resistant sealants for joints and gaps in building and infrastructure projects.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, hydroxyl value, and acid number to ensure consistent performance in downstream formulations. Certificates of Analysis (COA) detailing these specifications are provided and available upon request, supporting compliance with relevant industry standards for polymer raw materials.

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); containers must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
