Defoamers / Anti-foaming Agents

Based on 2077 products - Last update on the Jun 26, 2025

Defoamers are typically opaque to translucent liquids or pastes formulated to control and eliminate foam during the production, application, and drying of coatings. Functionally, they disrupt foam formation by breaking air bubbles and preventing their stabilization, resulting in smoother film formation and improved surface appearance. They are indispensable in architectural, industrial, and high-speed production coatings. 

Current trends in the coatings industry include the development of low-VOC, silicone-free, and bio-based defoamers that align with sustainability objectives while minimizing side effects like surface haze or poor recoatability. Available in oil-based, silicone-based, and polymer-based sub-types, these additives are selected based on resin compatibility and application method.
