Descripción

General description

Terminal secondary tetrahydroxy-functional oligomer.

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

Ethylenediamine tetrakis(ethoxylate-block-propoxylate) tetrol exhibits surface activity that varies with the EO/PO ratio. It offers lower foaming properties, enhanced defoaming capabilities, and reduced gelling tendencies compared to typical surfactants. Additionally, its terminal secondary hydroxyl groups exhibit lower reactivity and acidity than primary hydroxyl groups found in other surfactants, making it a versatile choice for various applications.
