In the fast-paced world of coatings and inks, formulators constantly seek materials that can enhance performance, improve processing, and meet stringent environmental standards. N-Vinylcaprolactam (NVCL), identified by CAS number 2235-00-9, stands out as a highly effective reactive diluent, particularly within UV-curing systems. As a leading supplier of high-quality NVCL, we understand its critical role in achieving superior results in various printing ink and coating applications.

What is a Reactive Diluent?

A reactive diluent is a low-viscosity monomer or oligomer that is incorporated into a formulation to reduce its viscosity, making it easier to process and apply. Unlike traditional solvents, reactive diluents are designed to participate in the polymerization process, becoming an integral part of the final cured film. This means they do not evaporate, contributing to lower VOC emissions and improved film properties.

N-Vinylcaprolactam: A Superior Choice for UV Systems

N-Vinylcaprolactam (NVCL) possesses several key characteristics that make it an ideal reactive diluent for UV-cured inks and coatings:

  • Low Viscosity: NVCL's inherent low viscosity allows formulators to achieve desired application viscosities with minimal addition, thereby minimizing the impact on the overall formulation cost and film properties.
  • High Reactivity: The vinyl group on NVCL readily participates in free-radical polymerization initiated by UV light, ensuring efficient curing and crosslinking.
  • Excellent Wetting and Adhesion: NVCL exhibits superior wetting properties on various substrates, including plastics and metals, which translates to improved adhesion of the final ink or coating. This is critical for demanding applications where long-term durability is required.
  • Improved Flexibility: Incorporating NVCL into formulations can enhance the flexibility of the cured film, making it more resistant to cracking or delamination, especially on flexible substrates.
  • Hydrophilic Character: The lactam ring imparts a degree of hydrophilicity, which can be beneficial in certain formulations and processing conditions.

Applications in UV Inks and Coatings

The versatility of N-Vinylcaprolactam makes it valuable across a broad spectrum of UV-curing applications:

  • Printing Inks: In UV screen printing and digital printing inks, NVCL contributes to faster curing speeds, better ink flow, improved adhesion to difficult substrates, and enhanced print quality. We are a trusted supplier for those looking to buy NVCL for their printing ink formulations.
  • Coatings: For industrial UV coatings, optical fiber coatings, and wood finishes, NVCL acts as a reactive diluent to improve flow, levelling, substrate wetting, and adhesion, while also contributing to the scratch resistance and overall durability of the coating.
  • Adhesives: NVCL's properties are also beneficial in UV-curable adhesives, where it can enhance bond strength and flexibility.
