Description

Poly(Dimer Acid-Co-Ethylene Glycol), Hydrogenated is a synthetic, saturated polyester resin derived from hydrogenated dimer acid and ethylene glycol. This chemical is valued for its excellent stability, flexibility, and hydrophobic character, making it a crucial intermediate and performance additive. It is primarily sought by manufacturers in the polymer, coatings, and adhesives industries seeking to enhance product durability and moisture resistance.

Application

• As a flexibilizing agent and hydrophobic modifier in polyurethane and epoxy resin formulations.
• Key intermediate in the synthesis of high-performance polyester polyols for coatings and elastomers.
• Used as a plasticizer and compatibilizer in specialty polymer blends and composites.
• Base material for formulating adhesives and sealants requiring good water resistance and low-temperature flexibility.
• Component in lubricant and grease formulations to improve viscosity and stability.
• Raw material for producing saturated polyester resins used in industrial and protective coatings.

Quality Control

Our Poly(Dimer Acid-Co-Ethylene Glycol), Hydrogenated is manufactured under a strict quality management system. Each batch is tested to ensure consistent properties such as acid value, hydroxyl value, viscosity, and color. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and oxidation.
