Name: VOK VOK-K3 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of VOK VOK-K3 Defoamer

High-efficiency silicone-based defoaming action with rapid knock-down and lasting foam suppression.
Excellent compatibility with water-based systems, including anionic, nonionic, and weakly cationic formulations.
Thermally stable up to 120°C, maintaining performance under elevated process temperatures.
Low dosage requirement—effective at 0.05–0.3% w/w in most industrial applications.
Non-silicone residue formulation ensures no coating defects or surface contamination in sensitive end uses.

Typical Applications Of VOK VOK-K3 Defoamer

Paints and coatings manufacturing, especially during pigment dispersion and let-down stages.
Industrial cleaning formulations, including alkaline and acidic CIP (Clean-in-Place) solutions.
Water treatment processes involving biological reactors and membrane filtration systems.
Papermaking wet-end systems to control foam during stock preparation and headbox operation.
Textile dyeing and finishing baths where persistent foam interferes with uniform application.
