Description

Hexanedioic acid, polymer with 1,4-butanediol, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, hydrazine, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, methyloxirane and oxirane CAS NO 99328-63-9 is a specialized polyurethane-polyol hybrid polymer. This engineered material offers a unique balance of flexibility, chemical resistance, and adhesion properties derived from its complex co-polymer structure. It is primarily utilized in the formulation of high-performance coatings, adhesives, and sealants where durability and specific functional characteristics are required.

Application

• High-Performance Industrial Coatings: Used as a key resin component in protective coatings for metal, concrete, and plastic substrates, offering excellent weatherability and chemical resistance.
• Specialty Adhesives and Sealants: Serves as a base polymer in formulating structural adhesives, potting compounds, and elastic sealants for automotive, aerospace, and construction applications.
• Elastomer and Rubber Modification: Acts as a modifier or cross-linking agent in polyurethane elastomers to enhance tensile strength, abrasion resistance, and low-temperature flexibility.
• Composite Materials: Employed in the production of fiber-reinforced plastics (FRP) and other composite materials as a matrix resin binder.
• Textile and Leather Finishes: Used in coatings and finishes to provide durable, flexible, and water-resistant surfaces.
• Electrical Encapsulation: Suitable for potting and encapsulating electronic components due to its good dielectric properties and adhesion.

Quality Control

Our polyurethane-polyol hybrid polymer undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters monitored include hydroxyl value, acid value, viscosity, and color. Certificates of Analysis (COA) detailing these specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management systems to guarantee reliability for your formulations.

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). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat, sparks, and open flame.
