In spray operations, the water curtain booth is a critical device for treating paint mist. However, paint residue and surfactants that accumulate in the circulating water can easily cause large amounts of foam to form. This stubborn foam not only overflows the water tank and contaminates the workshop environment, but also seriously reduces the uniformity of the water curtain and the efficiency of paint mist capture, ultimately affecting workpiece coating quality and increasing cleaning frequency and production costs.


Facing this common industry pain point, Chemi Tech has drawn on in-depth mechanism research to develop a series of high-efficiency defoamers specifically for water curtain booths. Our solution does not simply eliminate foam that has already formed; it suppresses foam generation at the source while quickly breaking existing foam. The product offers excellent compatibility and durability, maintaining high-efficiency performance even in complex water quality and chemical coexistence systems.


The implementation steps are clear and convenient. First, our technical staff evaluates your on-site water quality, coating type and foam condition; then we recommend a suitable defoamer grade and initial addition ratio. Under normal production conditions, the defoamer is added directly to the water curtain booth circulating water system. Depending on the foam suppression results, only small periodic top-up doses are needed thereafter to maintain a long-lasting foam-free state. The entire process does not affect the existing process flow or spray quality.


We once helped an auto parts manufacturer in East China tackle foam problems on its spray line. The company's water curtain booth suffered severe foam overflow, requiring the line to be stopped for cleaning several times per shift. After using our customized defoaming solution, the foam problem was significantly brought under control on the very first day, achieving two consecutive production shifts of overflow-free operation. The water curtain remained intact and uniform, paint mist treatment efficiency improved, and the workshop environment improved substantially, while reducing the waste of water and labor caused by shutdown cleaning.


Choosing Chemi Tech's high-efficiency defoamer means injecting a stabilizer into your spray production line. We are committed to helping you overcome foam obstacles through precise chemical solutions, safeguarding smooth production and improving final coating quality and overall operational efficiency.
