In the production, filling, and application of solvent-based coatings, foam often troubles many practitioners. These stubborn bubbles not only affect production efficiency and prolong the production cycle but also cause defects such as pinholes, cratering, or fish eyes on the final coating surface, seriously affecting the appearance and protective performance of the product. The market urgently needs an efficient, stable, and highly compatible solution.
In response to this core pain point, Chemi Tech, leveraging professional experience, has developed a series of efficient solvent-based coating defoamers. Our solution is based on an in-depth understanding of the foam generation mechanism and can break foam quickly and inhibit it durably. The defoamer products have good compatibility with solvent-based systems, will not cause side effects such as cratering or haziness, and ensure the stability of the coating system.
The specific solution is divided into three steps: first, add it during the early part of the grinding and dispersion stage of production to inhibit foam generation from the source; second, add a supplementary amount during the let-down stage according to the system's condition to eliminate bubbles introduced by stirring; finally, we provide application guidance for the construction stage to ensure good leveling and a bubble-free surface during spraying, brush coating, and other processes. Customers can choose the most suitable defoamer model and dosage according to their own formulation and process.
We once helped an industrial coatings manufacturer in East China solve the foam problem in its epoxy primer. The defoamer the customer originally used had a short foam-inhibiting duration, and tiny defects remained after the paint film dried. After analysis by Chemi Tech's technical team, we recommended a dedicated model and adjusted the addition stage and ratio. After application, the customer reported that the foam volume in the production process was reduced by more than 90%, the filling speed increased, and, more importantly, the final paint film surface was smooth and flat, significantly improving customer satisfaction.
Choosing Chemi Tech means choosing a reliable professional partner. We are committed to providing customers with comprehensive technical services that go beyond products alone, helping you leave behind foam troubles and improve coating quality and market competitiveness.
