Description

Hexanedioic Acid, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 1,3-Isobenzofurandione, Decanoate CAS NO 68936-87-8 is a specialized polymeric ester, synthesized from adipic acid, trimethylolpropane, and phthalic anhydride, terminated with a decanoate group. This engineered structure provides a unique balance of flexibility, hydrophobicity, and thermal stability, making it a valuable functional additive and intermediate. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in polymer modification and plasticizer applications.

Application

• Coatings & Resins: Acts as a polymeric plasticizer and modifier in alkyd, polyester, and polyurethane coatings to enhance flexibility, adhesion, and water resistance.
• Adhesives & Sealants: Used as a tackifier and flexibilizing agent to improve low-temperature performance and durability.
• Polymer Modification: Incorporated as a co-monomer or additive to modify the properties of base polymers, increasing impact strength and processability.
• Lubricant & Grease Additive: Serves as a viscosity modifier and thickening agent in synthetic lubricants and greases.
• Printing Inks: Functions as a resin component to improve pigment wetting, gloss, and film formation.
• Caulks & Putties: Imparts non-volatile plasticizing effects, reducing shrinkage and maintaining seal integrity over time.

Quality Control

Our production of this specialty polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, and color to ensure consistency and performance. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting 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 material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider purging the headspace with an inert gas such as nitrogen.
