Defoamer, Solvent-borne, Speciality Additive

VP 5057 Silicone-free defoamer

The 5057 Silicone-free Defoamer represents a specialized chemical solution engineered for industries where silicone contamination poses significant risks to surface quality and downstream processes. Formulated as a proprietary blend of hydrocarbon oils, fatty acid esters, and non-ionic surfactants, this high-performance additive effectively destabilizes entrained air and surface macro-foam without the adverse effects associated with polydimethylsiloxanes. Its molecular design ensures rapid dispersion in aqueous and non-aqueous media, providing immediate foam collapse while maintaining long-term suppression during high-shear operations. This defoamer is particularly critical in systems requiring subsequent bonding, painting, or coating, where silicone residues often lead to defects like “fish-eyes” or poor adhesion. By leveraging a unique interfacial tension mechanism, 5057 penetrates the surfactant film at the gas-liquid interface, causing rapid film drainage. It serves as a reliable alternative for manufacturers prioritizing process integrity, environmental compliance, and superior finish quality across diverse industrial fluid systems and complex chemical formulations quite effectively.

Attributes
