Description

Propanol, Oxybis-, Polymer With Bis(Isocyanatomethyl)Bezene And .Alpha.-Hydro-.Omega.-Hydroxypoly[Oxy(Methyl-1,2-Ethanediyl)] is a specialized polyurethane prepolymer or resin intermediate. This compound is engineered to deliver enhanced adhesion, flexibility, and chemical resistance in formulated end-products. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for developing high-performance materials.

Application

• High-Performance Coatings: Used as a key resin component in industrial, protective, and marine coatings for durability and weather resistance.
• Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and flexible sealants.
• Elastomer Production: Acts as a prepolymer in the manufacture of castable polyurethane elastomers for wheels, rollers, and gaskets.
• Composite Materials: Utilized as a matrix resin or binder in fiber-reinforced plastics and other composite systems.
• Textile & Leather Finishing: Employed in coatings and finishes to provide water repellency, abrasion resistance, and a soft hand feel.
• Automotive Components: Found in underbody coatings, interior trim adhesives, and vibration-damping materials.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Production is monitored against strict in-process controls for parameters such as isocyanate content, viscosity, and moisture. Certificates of Analysis (COA) detailing batch-specific results are available upon request, providing full traceability and assurance for your formulation 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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed to prevent exposure to atmospheric moisture, which can compromise product integrity. Keep away from heat, sparks, and open flames.
