Description

1,2-Ethanediamine, Polymer With 1,6-Diisocyanatohexane, Methyloxirane And Oxirane is a specialized polyether-polyurethane-urea block copolymer, CAS number 25302-25-4, engineered for high-performance applications requiring tailored rheological and mechanical properties. This versatile polymer is valued for its ability to act as a rheology modifier, dispersant, and film-forming agent, offering solutions for demanding formulation challenges. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science and specialty chemical synthesis.

Application

• High-Performance Coatings: Used as a rheology modifier and dispersing agent in automotive, industrial, and protective coatings to enhance flow, leveling, and pigment stabilization.
• Adhesives & Sealants: Serves as a key component in polyurethane-based adhesives and sealants, improving flexibility, adhesion, and durability.
• Elastomer Production: Acts as a chain extender or prepolymer in the manufacture of thermoplastic polyurethanes (TPU) and other elastomers, influencing hardness and elasticity.
• Textile & Leather Finishing: Employed in coatings and finishes to provide water resistance, softness, and improved handle to fabrics and leather goods.
• Composite Materials: Functions as a compatibilizer or toughening agent in polymer composites and fiber-reinforced plastics.
• Ink Formulations: Utilized as a dispersant and viscosity control agent in specialty printing inks.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, viscosity, isocyanate (NCO) content, and hydroxyl value to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided and available upon request, supporting compliance with relevant industry and customer-specific standards.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents.
