In industrial spraying operations, paint easily produces stubborn foam when circulating inside the spray booth. This foam can cause defects such as pinholes, shrinkage cavities, and fish eyes on the sprayed surface, seriously affecting the product's appearance and the protective performance of the coating. Frequent shutdowns for cleaning further cause material waste and reduced production efficiency. How to eliminate this foam stably and efficiently is a common challenge faced by many spray workshops.


To address this core pain point, Chemi Tech has developed a defoamer dedicated to paint spray booths. This product, through a specially designed formulation, can rapidly penetrate and destroy the foam film wall to achieve long-lasting foam suppression. It has good compatibility with various paint systems, does not affect the paint film's color, gloss, or subsequent adhesion, and provides a reliable guarantee for the smooth progress of the spraying process.


Our solution is specifically divided into three steps. The first step is problem diagnosis and sample matching. The technical team will learn in detail about the paint system you use, your spraying process parameters, and the specific manifestation of the current foam problem, and recommend the most suitable defoamer sample for testing. The second step is on-site testing and dosage determination. A small-scale addition test is carried out under your actual production conditions to precisely determine the optimal addition ratio; the usual dosage is one-thousandth to three-thousandths of the total paint amount. The third step is integrated application and effect tracking. The determined defoamer is integrated into your automatic dosing system or manual addition process, and the spraying quality and foam control are continuously tracked to ensure long-term, stable effectiveness.


For example, a metal products manufacturer located in East China found that when its spraying line used a certain type of polyurethane topcoat, foam accumulated seriously inside the spray booth, requiring a shutdown for cleaning every two hours, and the workpiece surface often had tiny pinholes. After adopting the Chemi Tech defoamer, and following a week of formulation adaptation and dosage optimization, the foam problem was fundamentally brought under control. The spray booth could run continuously for more than eight hours without cleaning, the coating surface of the workpieces was smooth and flat, the first-pass qualification rate was significantly improved, and paint loss was reduced by about fifteen percent.


Choosing Chemi Tech is not merely choosing a product, but obtaining a targeted foam control solution. We are committed to helping customers improve coating quality, reduce production costs, and achieve more efficient and more stable spraying operations.
