For chemists and material scientists working on advanced resin formulations, understanding the performance characteristics of key monomers is essential. 1,5-Pentanediol Diacrylate (CAS: 36840-85-4) is a high-performance chemical intermediate that offers significant advantages, particularly in UV-curing applications. This article explores its technical aspects and how it benefits resin formulators.

Technical Specifications and Properties

1,5-Pentanediol Diacrylate, with the chemical formula C11H16O4 and a molecular weight of 212.24, is a difunctional acrylate ester. Its physical form is typically a colorless to pale yellow liquid. Key technical data include a boiling point of 90-95 °C at 0.1 Torr and a density of approximately 1.024 ± 0.06 g/cm³. Purity levels commonly available are 97% or 98%, making it suitable for applications requiring precise molecular control and high performance. Its solubility in solvents like ethyl acetate is also a practical advantage for formulators.

Advancing UV Curing Technologies

The principal use of 1,5-Pentanediol Diacrylate lies in its role as a monomer in UV-cured polythiol resin systems. The two acrylate functionalities enable rapid and efficient crosslinking when exposed to UV light. This results in the formation of a highly crosslinked polymer matrix that provides excellent mechanical strength, chemical resistance, and thermal stability. Resin formulators seeking to buy this product are often aiming to improve:

  • Curing Speed: Faster processing times in manufacturing lines.
  • Hardness and Scratch Resistance: Enhanced durability for coatings and surface treatments.
  • Chemical Resistance: Improved performance against solvents and other chemicals.
  • Adhesion: Better bonding to various substrates.

Sourcing High-Quality 1,5-Pentanediol Diacrylate

When procuring 1,5-Pentanediol Diacrylate, R&D scientists and procurement specialists should prioritize suppliers who can guarantee consistent quality and purity. Working with established chemical manufacturers and distributors ensures access to materials that meet stringent specifications. For businesses looking to purchase this intermediate, understanding the available packaging options and minimum order quantities is also important for managing inventory and production schedules. For those requiring bulk supply, exploring options from global manufacturers, including those in China, can offer both quality and cost efficiencies.
