Description

Hexanedioic Acid, Polymer With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol And (Z)-9-Octadecenoic Acid is a specialized polymeric ester, commonly known as a polyester polyol or alkyd resin intermediate. This compound is engineered to provide a unique balance of flexibility, adhesion, and chemical resistance, making it a valuable building block for high-performance coatings and polymers. It is primarily sought by formulators in the paints & coatings, adhesives, and specialty plastics industries seeking to enhance product durability and functionality.

Application

• High-Performance Industrial Coatings: Used as a resin component in alkyd paints and polyurethane coatings for metal, wood, and plastic substrates, offering excellent gloss, adhesion, and weather resistance.
• Adhesives and Sealants: Serves as a key polyol in the formulation of flexible polyurethane adhesives and sealants, contributing to bond strength and elasticity.
• Plasticizers and Modifiers: Acts as a polymeric plasticizer or modifier for PVC and other polymers to improve impact resistance and low-temperature flexibility.
• Ink Resins: Utilized in the production of specialty printing inks, providing good pigment wetting and film-forming properties.
• Fiber and Textile Treatments: Employed in coatings for synthetic fibers and textiles to impart water repellency and durability.
• Cross-linking Agent: Functions as a reactive intermediate in thermosetting resin systems for composites and castings.

Quality Control

Our production of this polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including acid value, hydroxyl value, viscosity, and color index to ensure it meets the precise requirements of your formulation. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee traceability and compliance with your quality standards.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture which can affect product properties.
