"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.
