Description

Propylene Glycol-Neopentyl Glycol-4,4'-(1-Methylethylidiene)Bis-Cyclohexanol-Dipropylene Glycol-Maleic Anhydride is a high-performance, multi-functional polyester polyol intermediate designed for demanding industrial applications. This compound is valued for its ability to impart excellent hydrolytic stability, chemical resistance, and mechanical properties to final polymer products. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials and specialty plasticizers.

Application

• High-Performance Polyester Resins: A key building block for saturated polyester resins used in industrial and automotive coatings, coil coatings, and can coatings.
• Polyurethane Systems: Serves as a polyol component in the formulation of polyurethane dispersions (PUDs), elastomers, and adhesives requiring enhanced weatherability and durability.
• Specialty Plasticizers: Used in the synthesis of polymeric plasticizers that offer low volatility and superior migration resistance for PVC and other polymers.
• Composite Materials: Employed in resin systems for fiber-reinforced plastics (FRP) and composites where high strength-to-weight ratio and corrosion resistance are critical.
• Alkyd Resin Modifier: Incorporated to improve the drying time, hardness, and chemical resistance of modified alkyd resins.
• Industrial Adhesives & Sealants: Provides a robust backbone for adhesives and sealants used in construction, marine, and automotive applications.

Quality Control

Our production of this advanced polyester polyol intermediate adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can affect product performance.
