Describe
Dipentaerythritol hexaacrylate (DPHA or DPHAE) is a highly functional multi-acrylate monomer. Because it has 6 acrylate groups, it is widely used as a crosslinker with ultra-high crosslink density in UV/EB curing materials.

Physical and chemical properties
-
1. Chemical Identity
- Chemical Name: Dipentaerythritol hexaacrylate
- IUPAC Name: (3-Acryloyloxy-2,2-bis(acryloyloxymethyl)propoxy)methyl-2,2-bis(acryloyloxymethyl)propane-1,3-diyl diacrylate
- Synonyms: DPHA, Dipentaerythritol (6) acrylate
- CAS Number: 29570-58-9 (This CAS number also covers Ditrimethylolpropane tetraacrylate and other related polyol acrylates; it's often used for DPHA in technical literature and SDSs). A more specific, though less common, CAS is 60506-81-2.
- EC Number: 249-708-3
- Molecular Formula: C28?H34?O13?
- Molecular Weight: 578.56 g/mol
-
2. Physical Properties
- Appearance: Clear, colorless to pale yellow, highly viscous liquid. May appear as a waxy solid at room temperature.
- Odor: Mild, characteristic, acrylic/ester-like.
- Melting Point: Often handled at elevated temperatures (e.g., 50-60°C) to reduce viscosity.
- Boiling Point: >200 °C (>392 °F) (Decomposes)
- Density: 1.18 - 1.20 g/cm³ at 25 °C
- Solubility:
- In Water: Insoluble.
- In Organic Solvents: Soluble in many common organic solvents (e.g., ketones, esters).
- Vapor Pressure: <0.01 hPa at 20 °C
- Viscosity: Extremely high; typically >10,000 mPa·s at 25°C. Often reported at elevated temperatures (e.g., 200-500 mPa·s at 60 °C).
-
3. Chemical Properties and Stability
- Stability: Stable under recommended storage conditions. Typically supplied with a polymerization inhibitor (e.g., MEHQ).
- Incompatibilities: Incompatible with strong oxidizing agents, strong bases, strong acids, reducing agents, peroxides, and free-radical initiators.
- Hazardous Polymerization: May occur if not properly inhibited or if exposed to high temperatures, direct sunlight, UV radiation, or contaminants. Polymerization is a highly exothermic reaction.
- Hazardous Decomposition Products: Combustion may produce toxic fumes of carbon monoxide (CO) and carbon dioxide (CO2?).
