Description

Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Packaging

1 L in poly bottle

250 mL in poly bottle

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.

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.
