Water-based defoamers are environmentally friendly antifoaming agents that use water as the primary medium, employing specialized processes to emulsify active components like silicones and polyethers into stable dispersion systems. Their core mechanism involves surfactants enabling uniform dispersion of antifoaming active substances in water, forming mobile micro-droplet structures that promote foam collapse by reducing local surface tension and disrupting foam film elasticity. These defoamers demonstrate exceptional compatibility and self-emulsifying characteristics, allowing rapid dispersion in aqueous systems without leaving oil spots, making them particularly suitable for applications demanding high product transparency. They are widely used in water-based coatings, textile dyeing, paper manufacturing, industrial cleaning, and food processing industries, effectively controlling process foam while improving product quality, all while meeting modern industry's increasingly stringent environmental and safety requirements.
