Description

Propanoic acid, 3-hydroxy-2-(hydroxymethyl)-2-methyl-, polymer with 2-aminoethanol, 1,1'-methylenebis[4-isocyanatocyclohexane], 2-oxepanone and 2,2'-oxybis[ethanol] CAS NO 68052-34-6 is a specialized polyurethane or polyurethane-urea copolymer designed for high-performance applications. This advanced polymer is engineered to deliver a unique balance of flexibility, durability, and chemical resistance, making it a critical component in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty medical and electronic materials.

Application

• High-Performance Coatings: Used as a binder or resin in industrial, automotive, and protective coatings requiring excellent weatherability, abrasion resistance, and adhesion.
• Advanced Adhesives & Sealants: Serves as a key polymer in formulating structural adhesives, potting compounds, and flexible sealants for construction, aerospace, and automotive assembly.
• Specialty Elastomers: A base material for manufacturing cast or thermoplastic polyurethane (TPU) elastomers used in gaskets, rollers, and impact-resistant parts.
• Medical Device Coatings: Potential use in biocompatible coatings for medical devices, leveraging its polymerizable structure for controlled surface properties.
• Electronic Encapsulants: Employed in potting and encapsulation compounds to protect sensitive electronic components from moisture, vibration, and thermal stress.
• Fiber & Textile Finishing: Used to impart durable water repellency (DWR), softness, or other functional finishes to technical textiles.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is monitored through key parameters including solid content, viscosity, acid value, isocyanate (NCO) content (for prepolymers), and molecular weight distribution. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and potential quality degradation. Store away from incompatible materials such as strong acids, bases, and oxidizing agents.
