In the production and application of waterborne acrylate systems, foam often becomes a key bottleneck restricting product quality and production efficiency. Whether it is high-speed stirring during production or roller coating and brush coating during application, the stubborn foam generated not only affects production and filling efficiency but also causes defects such as cratering, fish eyes, and uneven gloss in the final coating film, seriously affecting the appearance and performance of the product.
The market commonly faces the pain points that traditional defoamers have poor compatibility and easily cause surface defects in the coating film; their foam-inhibiting durability is insufficient and cannot meet long-term application needs; and they perform unstably across various formulation systems, increasing the complexity of process debugging.
Chemi Tech focuses on the R&D of additives for waterborne systems, and the waterborne acrylate defoamer series we provide is a solution designed precisely for these core pain points. Our products use a composite technology of specially modified polysiloxane and organic polymers, offering excellent compatibility and foam-breaking efficiency. The specific application steps are as follows. First, add it in the early part of the grinding and dispersion stage of production to effectively inhibit the mechanical foam generated during stirring; second, add a supplementary amount during the let-down stage to ensure long-lasting foam-inhibiting performance during storage and application. The dosage is usually 0.1%-0.5% of the total formulation, and it is recommended to determine the optimal ratio through a small-scale trial.
We once helped an industrial coatings enterprise in East China solve the foam problem in its acrylic topcoat. The customer suffered severe foam overflow during the filling stage of the production line, and the finished paint showed a small number of pinholes in the paint film after spraying. By recommending and using our KT-328 defoamer, the customer added a 0.2% dosage during the grinding stage, successfully eliminating production foam and increasing the filling line efficiency by 15%. At the same time, the paint film surface was flat and smooth after drying, completely eliminating the pinhole problem, and the customer was satisfied with the final coating result.
