Description

Hexanedioic acid, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, 1,6-hexanediol, 1,3-isobenzofurandione and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a high-performance, cross-linked polyester-polyurethane resin designed for demanding industrial applications. This specialized polymer offers a unique balance of chemical resistance, mechanical strength, and durability, making it a critical raw material for advanced coatings and composites. It is primarily utilized by formulators and manufacturers in the protective coatings, industrial adhesives, and specialty plastics sectors seeking to enhance product performance.

Application

• High-Performance Industrial Coatings: Used as a key resin in formulations for chemical-resistant, abrasion-resistant, and weatherable coatings for metal, concrete, and plastic substrates.
• Protective Linings and Floorings: Serves as a base polymer for heavy-duty floor coatings, tank linings, and containment systems in chemical processing plants, wastewater facilities, and industrial manufacturing.
• Specialty Adhesives and Sealants: Imparts toughness and adhesion in structural adhesives, potting compounds, and sealants for automotive, aerospace, and construction applications.
• Fiber-Reinforced Composites: Acts as a matrix resin in composite materials, providing excellent interfacial bonding with glass or carbon fibers for lightweight structural components.
• Electrical Encapsulation: Employed in potting and encapsulation compounds to protect sensitive electronic components from moisture, vibration, and harsh environments.
• Automotive and Transportation Coatings: Formulated into primers, topcoats, and underbody coatings that require durability, chip resistance, and exposure to fuels and lubricants.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, acid value, and NCO content are rigorously monitored using modern analytical techniques including titration, GPC, and FTIR. Certificates of Analysis (COA) detailing all relevant specifications are 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 a controlled room temperature (typically 15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Store away from incompatible materials such as strong acids, bases, and oxidizing agents.
