| Application: | PPG-PEG-PPG Pluronic® 31R1 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: | 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. |
| General description: | Surface activity of the polymer is dependent on the EO/PO ratio. PPG-PEG-PPG exhibits lower foaming, greater defoaming and reduced gelling tendencies relative to Pluronic® surfactants. Terminal secondary hydroxyl groups of PPG-PEG-PPG have lower reactivity and acidity than the primary hydroxyl groups in Pluronic surfactants. |
