Description

Polyurethane Resin CAS NO 26680-22-8 is a versatile polymer material formed by the reaction of polyols with isocyanates. This product matters for its exceptional balance of durability, flexibility, and chemical resistance, making it a critical component in high-performance coatings and adhesives. Industries such as automotive manufacturing, construction, and industrial coatings rely on it to create products that withstand demanding environmental and mechanical stress.

Application

• Protective and Decorative Coatings: Formulating high-performance paints, varnishes, and topcoats for automotive, aerospace, and industrial equipment.
• Adhesives and Sealants: Manufacturing strong, flexible bonding agents for construction, footwear assembly, and composite material lamination.
• Elastomers and Molded Parts: Producing wheels, gaskets, seals, and other components requiring excellent abrasion resistance and elasticity.
• Textile and Leather Finishing: Used as a coating to provide water resistance, durability, and a desired aesthetic finish to fabrics and synthetic leather.
• Fiberglass Reinforced Plastics (FRP): Acting as the matrix resin in composite materials for marine, transportation, and sanitary ware applications.
• Flooring Systems: Formulating seamless, chemical-resistant, and durable industrial and commercial floor coatings.

Quality Control

Our Polyurethane Resin is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for key parameters such as viscosity, NCO/OH content, solids content, and color to ensure consistency and performance for your specific application. Certificates of Analysis (COA) are available upon request, and our quality protocols support compliance with relevant industry and regulatory standards.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures typically between 15-25°C (59-77°F). Due to its hygroscopic nature, prolonged exposure to atmospheric moisture must be avoided to prevent premature reaction and degradation of product quality.
