Propylene glycol n-butyl ether Usage And Synthesis
Industrial uses
The longer C4 alkyl carbon chain in propylene glycol n-butyl ether (PnB) affords more organic solvency as compared to the shorter methyl side chain group found in dipropylene glycol methyl ether (DPM). The PnB solvent is a better choice for a coalescent solvent than the DPM since the DPM solvent is completely water soluble. Complete water solubility limits the all important organic solubility necessary for good latex film formation.
