Product Description

Product Description

Basic Information

• Chemical Name: Dipentaerythritol Pentaacrylate
• Abbreviation: DPPA
• CAS Registry Number: 60506-81-2
• Molecular Formula: C25H32O12
• Molecular Weight: 524.51 g/mol

Physical and Chemical Properties

• Appearance: Colorless to pale yellow viscous liquid.
• Density: ~1.155 g/cm³ at 25 °C
• Flash Point: ~113 °C (closed cup)
• Refractive Index: n20/D ≈ 1.49
• Viscosity: High viscosity, suitable for formulating thick coatings and inks.
• Solubility: Soluble in common organic solvents (e.g., acetone, toluene); insoluble in water.

Reactivity and Polymerization

• Functionality: Contains five acrylate groups (CH2=CHCOO−), making it a highly reactive multifunctional monomer.
• Curing Mechanism: Undergoes rapid photocuring (radical polymerization) upon exposure to UV light or electron beams, forming cross-linked networks.
• Cross-Linking Efficiency: The five acrylate groups enable dense polymer networks, resulting in coatings with high hardness, chemical resistance, and mechanical strength.

Applications

• UV-Curable Coatings:
  • Used in wood, metal, and plastic coatings for furniture, electronics, and automotive parts, providing scratch resistance and gloss.
• Printing Inks:
  • Formulates high-opacity UV inks for packaging (e.g., labels, cartons) and flexographic printing, ensuring fast drying and color stability.
• Adhesives and Sealants:
  • Enhances bond strength in UV-curable adhesives for glass, ceramics, and plastics; suitable for optical applications (e.g., fiber optic coatings).
• 3D Printing and Photopolymers:
  • Serves as a cross-linking agent in stereolithography (SLA) resins, contributing to the rigidity and dimensional accuracy of 3D-printed parts.
• Composite Materials:
  • Reinforces dental composites and medical devices due to its biocompatibility (when purified) and resistance to chemical degradation.

Safety and Handling

• Health Hazards:
  • Inhalation may irritate the respiratory system; skin contact can cause irritation or sensitization.
  • Eye contact is harmful and may lead to severe irritation; ingestion is toxic if swallowed.
• Environmental Risks:
  • Low volatility reduces air pollution, but improper disposal may harm aquatic life (check local regulations for waste management).
• Precautions:
  • Use protective gloves, goggles, and ventilation during handling.
  • Store in a cool, dark place away from oxidizing agents and UV sources to prevent premature curing.
