General description

ElectroGreen® solvents—our bio-based alternatives that are meticulously engineered to meet the stringent requirements of electronics and energy applications, offering a solution to replace fossil-based solvents.
Our tailored products offer:
  • High purity (GC)
  • Low residue in evaporation (RESE)
  • Low metal content (ICP)
  • Low water content (KF)
  • Low acidity
  • Low toxicity and VOC
  • Accessible cost
This ElectroGreen® solvent is made of bio-based (corn/beets-derived) safer alternatives to replace synthetic NMP fossil-based solvent with specifications tailored for electronics and energy applications. All our ElectroGreen® solvents line are derived from a renewable resource (verified through C14 ASTMD6866-16 testing). We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Click here for more information.

This solvent blend consists of Dimethyl sulphoxide 50-70%; N,N-Dimethyloctanamide 20-30%; N,N-Dimethyldecan-1-amide 10-20%.

Application

N-Methyl Pyrrolidone (NMP)’s largest use in electronics is in cleaning, surface preparation applications and ink formulations. For coatings formulators looking to replace petroleum-based solvents with a bio-based, sustainable alternative, NMP substitute – type 2, bio-sourced is a solvent blend ideal replacement for NMP in a wide array of ink formulations and cleaning applications.

Our ElectroGreen solvent facilitates the preparation of cathode slurry for Li-ion and Li-S based batteries in a shorter time compared to NMP, demonstrating enhanced scalability and reduced capacity loss per cycle across various discharge current rates, indicating no degradation of the material.

Preparation Note

To ensure low water content, handle under inert conditions. Product should be refrigerated upon receipt.
