Description

Polyurethane Resin CAS NO 67700-43-0 is a versatile polymer material formed by the reaction of polyols with isocyanates, creating a backbone with exceptional durability and flexibility. This product is engineered to deliver superior performance in demanding applications, offering an optimal balance of mechanical strength, chemical resistance, and processability. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producers of specialty foams and composites.

Application

• Protective & Decorative Coatings: Formulating high-performance industrial, automotive, and wood coatings for superior abrasion resistance, gloss, and weatherability.
• Adhesives & Sealants: Serving as a key component in structural adhesives, laminating adhesives, and flexible sealants requiring strong bonding and elasticity.
• Elastomers and Castables: Manufacturing of wheels, rollers, gaskets, and industrial parts that demand high tensile strength, tear resistance, and load-bearing capacity.
• Foam Systems: Production of flexible, semi-rigid, and rigid foams for applications in insulation, cushioning, and packaging.
• Composite Materials: Used as a matrix resin in fiber-reinforced plastics (FRP) for lightweight, high-strength components.
• Textile & Leather Finishing: Providing durable, flexible coatings and finishes for synthetic leather, waterproof fabrics, and other technical textiles.

Quality Control

Our Polyurethane Resin is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, solids content, and mechanical properties are rigorously tested against internal and customer specifications. A Certificate of Analysis (COA) detailing all relevant test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade (typically between 15°C to 25°C). This material is hygroscopic (moisture-sensitive); prolonged exposure to atmospheric humidity must be avoided to prevent premature reaction and gelation.
