Description

Hexanedioic Acid, Polymer With 1,3-Isobenzofurandione And 1,2-Propanediol, Diesters With C8-18 And C18-Unsatd. Fatty Acids is a specialized polymeric ester, commonly known as a complex alkyd or polyester resin. This product matters as a high-performance, film-forming polymer that provides excellent adhesion, flexibility, and durability in formulated coatings. It is primarily needed by manufacturers in the paints, coatings, inks, and adhesive industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: As a key resin binder in solvent-borne and high-solids coatings for metal, wood, and plastic substrates.
• Printing Inks: Used in flexographic and gravure inks to improve gloss, adhesion, and rub resistance.
• Adhesives and Sealants: Acts as a tackifying and film-forming agent to enhance bond strength and flexibility.
• Plasticizers and Modifiers: Incorporated into polymer blends to modify flexibility, processability, and impact resistance.
• Specialty Additives: Serves as a base for rheology modifiers or dispersing agents in complex formulations.

Quality Control

Our production of this polymeric ester adheres to strict quality management systems. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, and color to ensure batch-to-batch consistency for your formulations. Certificates of Analysis (COA) documenting these specifications are available upon request, supporting compliance with relevant industry standards.

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 easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen blanket) to preserve quality and prevent skin formation.
