Descrizione

Descrizione generale

Terminal secondary tetrahydroxy-functional oligomer.

Applicazioni

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.

Caratteristiche e vantaggi

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.
