In spray coating operations, the circulating water system of a paint booth often suffers from foam accumulation. This foam not only affects the spraying effect, causing defects on the paint surface, but also clogs filtration equipment, increases the burden of water treatment, and even causes overflow that pollutes the working environment. Traditional defoaming methods often have only a short-lived effect and require frequent addition, wasting resources while failing to eliminate the problem at its root.
To address this pain point, Chemi Tech has developed a defoamer dedicated to paint booth wastewater. This product uses a special formulation that can rapidly penetrate and destroy the foam film structure to achieve instantaneous defoaming. Its durable foam-suppressing performance can effectively prevent foam from regenerating. It is suitable for various water-based paint and resin systems and remains stable over a wide pH and temperature range.
The specific solution is divided into three steps: First, analyze the composition of the paint booth wastewater and the causes of foam generation; second, based on water quality and process conditions, recommend a suitable Chemi Tech defoamer model and dosage ratio; finally, guide the customer to add the defoamer into the circulating water tank or pipeline, usually by direct dripping or spraying after dilution, and the foam can be observed to dissipate rapidly.
A real application case shows that an automotive parts coating company long troubled by foam saw its foam problem brought significantly under control within 24 hours after using Chemi Tech defoamers. The circulating water system ran more smoothly, the frequency of filter replacement decreased, the paint spraying quality improved, and the overall maintenance cost was saved by nearly 30%. The company stated that the defoamer's efficiency and cost-effectiveness exceeded expectations.
