"Pyrrolidone-based solvents" for special solvents (solvents, stripping agents, cleaning agents, etc.).
We handle "pyrrolidone-based solvents" used in solvents, co-solvents, photoresist stripping solutions, cleaning/stripping agents, wetting agents, etc.!
The acetylene derivatives handled by our company are a product group derived from acetylene. We deal with products used in a wide range of fields, including solvents, surfactants, monomers, and functional polymers. Our company has been engaged in sales activities in Japan for many years and supports our customers' product development with extensive product knowledge. We would like to introduce "pyrrolidone-based specialty solvents" manufactured from acetylene derivatives. 【Representative Products】 ■ γ-Butyrolactone (GBL) ■ 2-Pyrrolidone ■ N-Methyl-2-pyrrolidone (NMP) ■ N-Ethyl-2-pyrrolidone (NEP) ■ N-Hydroxyethyl-2-pyrrolidone (HEP) *For more details, please refer to the PDF materials or feel free to contact us.

Applications/Examples of results
【Representative Uses】 <γ-Butyrolactone (GBL)> Can be used as a solvent for inkjet inks, industrial cleaners, and resin solvents. <2-Pyrrolidone> Can also be used as a solvent for printing inks and as a plasticizer for resins. <N-Methyl-2-pyrrolidone (NMP)> Widely used for cleaning electronic devices, coating, photoresist stripping, and as a solvent for secondary batteries. <N-Ethyl-2-pyrrolidone (NEP)> Can be used alone or in combination with other water-soluble solvents. It can also serve as an alternative to N-Methyl-2-pyrrolidone. <N-Hydroxyethyl-2-pyrrolidone (HEP)> Can be used as a solvent for photoresist strippers, paint strippers, and other cleaning agents, either alone or in combination with other solvents. *For more details, please refer to the PDF document or feel free to contact us.
