At a medium-sized coating factory in Jiangsu, technician Wang was struggling with stubborn foam issues. Their newly developed high-solid coating generated excessive foam during filling, affecting both efficiency and product quality. After trying various defoamers in vain, they turned to Chemi Tech Polyurethane Defoamer and solved the months-long problem in just three days.

Three Advantages of Chemi Tech Polyurethane Defoamer

1、Highly Effective & Long-Lasting
The unique polyurethane structure ensures both rapid foam collapse and long-term suppression. An ink manufacturer in Zhejiang reported it solved both mixing foam and storage foam issues.
2、Excellent Compatibility
Blends perfectly with systems without causing craters or fish eyes. An adhesive producer in Shandong confirmed it maintained product clarity and bonding strength.
3、Wide Applicability
Works effectively in both water-based and oil-based systems, under high or normal temperatures. Tests at 80°C in a Guangdong industrial coating line showed outstanding performance.
