In the dynamic world of UV-curable coatings, selecting the right monomer is paramount to achieving desired performance characteristics. Polyethylene Glycol Diacrylate (PEGDA) stands out as a versatile building block, with various molecular weights offering distinct properties. For formulators looking to strike a balance between flexibility, adhesion, and curing speed, PEG-400 DA is often the preferred choice. As a leading manufacturer and supplier of specialty chemicals, understanding the nuances of these monomers can help you optimize your formulations and secure the best price for your raw materials.

PEGDA is a bifunctional monomer featuring two acrylate groups connected by a polyethylene glycol chain. The '400' in PEG-400 DA refers to its average molecular weight of the PEG chain. This specific molecular weight provides a unique combination of hydrophilicity, low volatility, and good ductility, making it an excellent diluent and crosslinker in UV-curable systems. Unlike lower molecular weight PEGDAs which might be more brittle, or higher molecular weight PEGDAs which can increase viscosity significantly, PEG-400 DA offers a balanced profile.

Why Choose PEG-400 DA for Your Coatings?

  • Enhanced Flexibility and Toughness: The longer, more flexible PEG chain in PEG-400 DA imparts a greater degree of flexibility and impact resistance to the cured film. This is crucial for coatings applied to substrates that may undergo bending or flexing, preventing cracking and delamination.
  • Improved Water Solubility and Hydrophilicity: Its water-soluble nature simplifies formulation and allows for easier cleanup. This characteristic can also be beneficial in applications where a degree of surface wettability is desired.
  • Low Volatility: Compared to monofunctional monomers, PEG-400 DA exhibits lower volatility, contributing to a safer working environment and reduced VOC emissions.
  • Balanced Reactivity: PEG-400 DA offers a good balance of reactivity, ensuring efficient curing under UV light without being excessively fast, which could lead to shrinkage or stress in the coating.
