Description The surface activity of the polymer depends on the EO/PO ratio. PPG-PEG-PPG exhibited lower foam, greater defoaming and lower tendency to gel. The terminal secondary hydroxyl groups of PPG-PEG-PPG are less reactive and acidic than the primary hydroxyl groups in other surfactants.

Application Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.
PPG-PEG-PPG can be used as surface cleaners (soft and hard), defoamers in coatings, in water treatment, lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.

Features And Benefits Features and Benefits
Surface activity is dependent on the EO/PO ratio. Lower foaming, greater defoaming and reduced gelling tendencies relative to Pluronic® surfactants. Terminal secondary hydroxyl groups have lower reactivity and acidity than the primary hydroxyl groups in Pluronic® surfactants.
