Dipentaerythritol

Dipentaerythritol (CAS 126-58-9), also known commercially as Dipentek and abbreviated as DiPE, is a high-functionality polyol produced as a co-product in pentaerythritol manufacturing.

Where is Dipentaerythritol used?

• Coatings, adhesives and polymers: reactive building block for high-performance resins, esters and crosslinked polymer systems
• Alkyd and radiation-curable coatings: reacts with fatty acids and isocyanates for resins with superior hardness, durability and crosslink density
• Lubricant esters: synthetic esters with high thermal stability and low volatility for aerospace and industrial applications
• UV-curable adhesives and sealants: core acrylate ester intermediate for tight network formation and fast cure
• Personal care: DiPE-derived esters serve as emollient carriers and film-forming agents in long-wear cosmetics.

Commercial specifications

• Purity typically 90% minimum for most uses
• High-purity grades target ester synthesis with tighter hydroxyl value specifications
