Effective Solutions for Bubble Issues in Thick Coatings

Bubble formation during the production and application of thick coatings can compromise film uniformity and surface finish. Residual bubbles may lead to pinholes, craters, or reduced adhesion, ultimately affecting product performance. To address this challenge, Chemi Tech has developed defoamers specifically designed for high-viscosity coating systems. Their advanced chemical formulation rapidly eliminates existing foam and suppresses re-foaming.  

The key advantage of Chemi Tech defoamers lies in their exceptional compatibility and longevity. The molecular structure penetrates foam lamellae efficiently, disrupting surface tension to collapse bubbles instantly. These defoamers remain stable under high-temperature and high-shear conditions, making them ideal for epoxy, polyurethane, and other viscous coatings. Field tests confirm that Chemi Tech defoamers improve flow properties and film formation, boosting application efficiency by over 20%.  

Moreover, Chemi Tech’s technical team provides tailored solutions based on customer formulations, ensuring optimal integration with coating systems. Whether addressing mixing-induced foaming during production or mechanical foaming during application, precise dosage control delivers consistent results.
