DOWFAX™ 63N40 Nonionic Surfactant

DOWFAX™ 63N40 Nonionic Surfactant by Dow is linear EO/PO block copolymer. It is a surfactant and foam control agent. It is produced by polymerizing ethylene oxide (EO), propylene oxide (PO), and/or butylene oxide (BO) in the same molecule. The optimum operating temperature range for wetting and low foam control is +/- 10°C of the surfactant’s cloud point in that system. DOWFAX™ 63N40 Nonionic Surfactant possesses good wetting ability, high degree of detergency and low foam characteristics. It also shows reverse water solubility.
