Q1: What is the primary function of Plurafac LF 431 in industrial formulations?
A: Plurafac LF 431 is a nonionic surfactant designed primarily for wetting, emulsification, and solubilization in aqueous systems. It is especially valued for its low-foaming behavior and good compatibility with electrolytes, making it suitable for cleaning, agrochemical, and industrial maintenance applications.
Q2: Is Plurafac LF 431 compatible with acidic or alkaline conditions?
A: Yes, Plurafac LF 431 exhibits broad pH stability and performs reliably across a wide pH range, including mildly acidic to strongly alkaline environments commonly encountered in industrial cleaners and process formulations.
Q3: How does Plurafac LF 431 compare to other Plurafac grades in terms of foaming tendency?
A: Plurafac LF 431 is specifically engineered as a low-foaming variant within the Plurafac family. Compared to standard Plurafac grades like LF 22 or LF 400, it delivers significantly reduced foam generation while maintaining effective surface activity—ideal for high-shear or recirculating systems where foam control is critical.
Q4: What are typical dosage guidelines when using Plurafac LF 431 in cleaning formulations?
A: Dosage depends on formulation requirements and performance targets, but Plurafac LF 431 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in aqueous cleaning concentrates and ready-to-use solutions.
