Foam Issues in Waterborne Polyurethane? Chemi Tech’s High-Efficiency Solution

In the coating production workshop, Zhang stared at the foam surging in the mixing tank, his brow furrowed. This batch of waterborne polyurethane material was highly sensitive to foam—excessive bubbles not only affected film formation but also caused surface defects. Even after multiple adjustments to process parameters, the problem persisted.

Then, the technical team recommended Chemi Tech’s waterborne polyurethane defoamer.

Chemi Tech’s defoamer features a unique molecular design that rapidly penetrates foam films and destabilizes them. Upon addition, the foam dissipated quickly, restoring smooth production flow. To Zhang’s surprise, the defoamer exhibited excellent compatibility with the system, neither compromising coating transparency nor causing craters or fisheyes.

“The results were immediate,” Zhang noted in his weekly report. “Product pass rates increased by 15%.”

Chemi Tech’s R&D engineer explained, “Our defoamer is optimized for waterborne polyurethane systems, combining foam suppression and bubble-breaking functions. It performs stably even under high-speed stirring or elevated temperatures.”

Today, this defoamer has become an “invisible guardian” in many production lines. Quiet yet indispensable, it ensures consistent quality in every batch.
