Description

Hexanedioic Acid, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, (9Z)-9-Octadecenoate is a specialized polymeric ester derived from adipic acid, trimethylolpropane, and oleic acid. This unique chemical structure provides excellent compatibility and plasticizing effects in polymer systems, making it a valuable functional additive. It is primarily utilized in the formulation of high-performance coatings, adhesives, and sealants where enhanced flexibility, adhesion, and moisture resistance are critical.

Application

• As a plasticizer and flexibilizer in polyurethane and polyester resin formulations for coatings and adhesives.
• Key component in the production of alkyd resins for industrial and decorative paints, improving film formation and durability.
• Used as a modifying agent in sealants and caulks to enhance elasticity and long-term performance.
• Functional additive in printing ink vehicles to adjust viscosity and improve pigment wetting.
• Intermediate for synthesizing specialty lubricants and release agents.
• Raw material in the manufacture of polymer dispersions for textile and leather finishing.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including acid value, hydroxyl value, viscosity, and color. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture which may affect product properties.
