설명

일반 설명

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.

애플리케이션

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 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.

특징 및 장점
