Description

1,3-Isobenzofurandione, Polymer With 1,2-Ethanediol, [Tetradecahydro-1,4A-Dimethyl- 7-(1-Methylethyl)-1-Phenanthrenyl]Methyl Ester is a specialized polymeric ester derived from phthalic anhydride and a diterpene alcohol, offering unique properties as a tackifier and modifier. This compound matters for its ability to enhance adhesion, flexibility, and compatibility in demanding polymer formulations. It is primarily needed by manufacturers in the adhesives, sealants, coatings, and specialty polymer industries seeking to improve product performance.

Application

• Adhesive Formulations: Acts as a tackifier and compatibility enhancer in pressure-sensitive and hot-melt adhesives.
• Sealant Production: Used to modify rheology and improve the cohesive strength of industrial and construction sealants.
• Polymer Modification: Serves as a plasticizer and compatibilizer in specialty rubber and plastic compounds to adjust flexibility and processability.
• Coating Resins: Incorporated into coatings to improve film-forming properties, adhesion to difficult substrates, and durability.
• Ink Manufacturing: Utilized as a resin modifier in specialty printing inks to enhance gloss and substrate wetting.

Quality Control

Our production of this polymeric ester adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including acid value, softening point, color, and viscosity to meet precise customer requirements. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment.

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). Keep away from heat sources and open flames. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided.
