2-PYROL 2-Pyrrolidone International Specialty Products Film forming /coalescing agents Plasticizer Solvent Humectant Acrylic/Acrylate Resins Inks Printing Inks & Varnishes >> Digital inks (eg. Ink jet) Pyrrolidones: This family of chemicals varies in properties as a function of substitution on the lactam nitrogen atom. All members are characterized by low vapor pressure, high flash point, high dipole moment, ready complex formation, surface activity as the alkyl chain lengthens and biodegradability when the alkyl chain is linear. 2-PYROL®, the first member, is used as a humectant, cosolvent with water, coalescent aid and plasticizer. 2-PYROL® (2-Pyrrolidone) Humectant and cosolvent in digital printing inks Coalescent or plasticizer for acrylic resins, especially in floor polishes, inks and adhesives The reactive site of 2-PYROL® is its labile hydrogen on nitrogen. It can undergo vinylation with acetylene, alkylation with alkylhalides and acylation with acylhalides. Hydrolysis in basic media produces y-aminobutyric acid. hygroscopic lubricant complexing agent solubilizer solvent biodegradable reactive Hygroscopic, biodegradable and reactive 2-pyrrolidone. Used as a humectant and cosolvent in digital printing inks and as a coalescent or plasticizer for acrylic resins, especially in inks. Offers low vapor pressure, high flash point, high dipole moment, ready complex formation and surface activity.
